Description
技术领域Technical Field
本发明属于仓储物流技术领域，尤其涉及一种易溶解和挥发的危化品泄漏扩散模型的构建方法、接收用户输入程序存储介质、存储在计算机可读介质上的计算机程序产品、在海洋运输危化品中的应用。The present invention belongs to the field of warehousing and logistics technology, and in particular relates to a method for constructing a leakage and diffusion model of easily soluble and volatile hazardous chemicals, a storage medium for receiving user input program, a computer program product stored on a computer-readable medium, and its application in marine transportation of hazardous chemicals.
背景技术Background Art
一般情况下，危化品均以液态形式进行海上运输，但其泄漏进入海洋后，由于密度、溶解度、挥发性等性质千差万别，导致的运动形式也不尽相同。总的来说，性质相近的危化品以某一主要运动形式为主，目前关于海上危化品泄漏扩散类型主要包括4类：(1)不溶于水的，在水面以二维形式进行输移和扩散，如油类物质；(2)易溶于水的，较均匀地分布在水体中，以三维形式输移、扩散，包括各类无机酸和碱；(3)难溶于水且比重大于或接近于水的，沉降至水底或悬浮在水体中进行输运，如氯苯；(4)挥发性强的，直接进入大气中进行输移和扩散，如液氨。于是，根据这四类运动形式，将海上危化品对应地为漂移型、溶解型、悬浮型和易挥发性型四种类型(见表1)。Generally speaking, hazardous chemicals are transported by sea in liquid form. However, after they leak into the ocean, their density, solubility, volatility and other properties vary greatly, resulting in different forms of movement. In general, hazardous chemicals with similar properties mainly move in one main form. Currently, there are four main types of hazardous chemical leakage and diffusion at sea: (1) Those that are insoluble in water, migrate and diffuse in two dimensions on the water surface, such as oil substances; (2) Those that are easily soluble in water, are relatively evenly distributed in the water body, migrate and diffuse in three dimensions, including various inorganic acids and alkalis; (3) Those that are difficult to dissolve in water and have a specific gravity greater than or close to that of water, sink to the bottom of the water or float in the water body for transportation, such as chlorobenzene; (4) Those that are highly volatile, directly enter the atmosphere for transportation and diffusion, such as liquid ammonia. Therefore, according to these four forms of movement, hazardous chemicals at sea are divided into four types: drift type, dissolved type, suspended type and volatile type (see Table 1).
表1危化品模型总结Table 1 Summary of Hazardous Chemicals Model
其中，前三种模型基本都以模块形式耦合在海洋模式中(如ROMS和FVCOM等区域海洋模式)，其中海面漂移型和悬浮输移型采用粒子(floats)模块，溶解扩散型多采用惰性示踪物(tracer)模块。而易挥发型基本以示踪物模块形式耦合在大气模式中，例如WRF模式中的惰性示踪物(passive tracer)模块，WRF-chem模式的各类污染物模块。Among them, the first three models are basically coupled to the ocean model in the form of modules (such as regional ocean models such as ROMS and FVCOM), among which the sea surface drift type and suspended transport type use the particle (floats) module, and the dissolved diffusion type mostly uses the inert tracer (tracer) module. The volatile type is basically coupled to the atmospheric model in the form of a tracer module, such as the inert tracer (passive tracer) module in the WRF model and various pollutant modules in the WRF-chem model.
以往的研究多基于上述的四种模型，单独采用海洋模式开展漂移型、悬浮型和溶解型危化品泄漏的数值模拟工作，或者单独采用大气模式开展易挥发性危化品的数值模拟工作，模拟的情况比较单一。真实的危化品泄漏事件中，有的类型的危化品会在海表处会存在挥发。如苯乙烯属于海面漂移型危化品，但同时又易挥发。液氨，凝析油等危化品属于溶解型危化品，但同时在海表也易挥发。因此需要考虑危化品泄漏入海后，在海洋中和大气中的共同输移扩散。例如2001年4月的长江口大勇轮泄漏事件，大勇轮泄漏了大量的苯乙烯，苯乙烯漂浮于海面，随着海水流动在海面上不断扩散，污染长江口海域，同时又不断挥发进入到大气中，对泄漏区域周围的大气产生污染。而2018年1月份发生的桑吉轮事件中，桑吉轮沉没入海后携有大量的凝析油，凝析油是一种轻质油，可以溶于水，入水后在海表会快速挥发、容易被自然风化。国内外研究表明，凝析油5小时左右挥发量大概达到99％；24小时内，几乎完全挥发。因此桑吉轮沉没后泄漏的凝析油在海水中以三维形式输移扩散，当垂向运动到海洋表层时，会快速挥发到大气中，从而在大气中漂移扩散。Previous studies were mostly based on the above four models, using ocean models alone to carry out numerical simulations of drifting, suspended and dissolved hazardous chemicals, or using atmospheric models alone to carry out numerical simulations of volatile hazardous chemicals. The simulations were relatively simple. In real hazardous chemical leaks, some types of hazardous chemicals will volatilize on the sea surface. For example, styrene is a type of hazardous chemical that drifts on the sea surface, but it is also volatile. Hazardous chemicals such as liquid ammonia and condensate oil are soluble hazardous chemicals, but they are also volatile on the sea surface. Therefore, it is necessary to consider the common transport and diffusion of hazardous chemicals in the ocean and the atmosphere after they leak into the sea. For example, in the Dayong ship leak at the Yangtze River estuary in April 2001, the Dayong ship leaked a large amount of styrene. Styrene floated on the sea surface and continued to spread on the sea surface with the flow of seawater, polluting the Yangtze River estuary. At the same time, it continued to volatilize into the atmosphere, polluting the atmosphere around the leak area. In the Sanchi incident in January 2018, the Sanchi sank with a large amount of condensate oil. Condensate oil is a light oil that can be dissolved in water. After entering the water, it will evaporate quickly on the sea surface and be easily weathered by nature. Domestic and foreign studies have shown that the condensate oil evaporates about 99% in about 5 hours; within 24 hours, it evaporates almost completely. Therefore, the condensate oil leaked after the Sanchi sank was transported and diffused in the seawater in a three-dimensional form. When it moves vertically to the surface of the ocean, it will evaporate quickly into the atmosphere, thereby drifting and diffusing in the atmosphere.
上述的危化品泄漏过程简单概括为：危化品泄漏入海后迅速溶解于海水，在海洋内部输移和扩散，到达海洋表层的危化品则以一定的速率挥发进入到大气底层中，进而在大气中三维输移和扩散。目前单一的危化品泄漏模型难以刻画危这类海气界面的危化品泄漏输移扩散过程。The above-mentioned hazardous chemical leakage process can be simply summarized as follows: after the hazardous chemicals leak into the sea, they quickly dissolve in the seawater, and are transported and diffused in the ocean. The hazardous chemicals that reach the surface of the ocean evaporate into the bottom layer of the atmosphere at a certain rate, and then are transported and diffused in three dimensions in the atmosphere. At present, a single hazardous chemical leakage model is difficult to describe the transport and diffusion process of hazardous chemical leakage at the sea-air interface.

Hazardous chemicals on the surface of the ocean evaporate into the atmosphere at a certain rate, causing the concentration of hazardous chemicals on the surface to decay, while the volatilized hazardous chemicals enter the bottom layer of the atmosphere and are then transported and diffused in the atmosphere in three dimensions.
将该模型嵌入到大气-海洋耦合模式系统中，实现溶解-挥发型危化品泄漏后在海洋和大气中的输移和扩散的数值模拟，模拟结果包括危化品泄漏后在海洋中和大气中的三维浓度分布和时间变化。The model is embedded in the atmosphere-ocean coupled model system to realize the numerical simulation of the transport and diffusion of dissolved-volatile hazardous chemicals in the ocean and atmosphere after leakage. The simulation results include the three-dimensional concentration distribution and time variation in the ocean and atmosphere after the leakage of hazardous chemicals.

其中t为时间；x、y、z空间位置坐标；u、v、w为x、y、z方向的流速分量(m/s)；Kx为x方向的涡动扩散系数(m2/s)；Ky为y方向的涡动扩散系数(m2/s)；Kz为z方向的涡动扩散系数(m2/s)；vθ为分子扩散系数(m2/s)；C为水体中污染物的浓度(g/m3)；FC为污染物的源强(g/m3·s)，DC为污染物的耗散项(g/m3·s)，减少的VC1为海洋表层危化品挥发导致的浓度降低(volatilization作用，单位为g/m3·s)。Where t is time; x, y, and z are spatial position coordinates; u, v, and w are flow velocity components in the x, y, and z directions (m/s); Kx is the eddy diffusion coefficient in the x direction (m 2 /s); Ky is the eddy diffusion coefficient in the y direction (m 2 /s); Kz is the eddy diffusion coefficient in the z direction (m 2 /s); vθ is the molecular diffusion coefficient (m 2 /s); C is the concentration of pollutants in the water body (g/m 3 ); FC is the source intensity of the pollutant (g/m 3 ·s), DC is the dissipation term of the pollutant (g/m 3 ·s), and the reduced VC1 is the concentration reduction caused by the volatilization of hazardous chemicals in the surface ocean (volatilization effect, unit is g/m 3 ·s).
在一个实施例中，溶解-挥发型危化品的三维扩散时大气底层的扩散方程为：In one embodiment, the diffusion equation of the bottom layer of the atmosphere during the three-dimensional diffusion of dissolved-volatile hazardous chemicals is:
增加的VC2为海洋的挥发的危化品进入大气中导致危化品浓度增加(单位为g/m3·s)。The increased VC2 is the volatile hazardous chemicals from the ocean entering the atmosphere, resulting in an increase in the concentration of hazardous chemicals (in g/m 3 ·s).
在一个实施例中，溶解-挥发型危化品的三维扩散时，海洋下层的扩散方程为：In one embodiment, when dissolved-volatile hazardous chemicals diffuse in three dimensions, the diffusion equation of the lower ocean layer is:
在一个实施例中，溶解-挥发型危化品的三维扩散时，大气上层的扩散方程为：In one embodiment, when dissolved-volatile hazardous chemicals diffuse in three dimensions, the diffusion equation in the upper atmosphere is:
其中海洋表层危化品挥发量的计算参考半衰期浓度计算公式，设t时刻，海洋表层的危化品浓度为Ct，危化品挥发的半衰期为T，dt为计算时间步长，则t+dt时刻，海洋表层的危化品浓度为
海洋表层挥发的危化品都进入到大气底层，因为大气底层厚度跟海洋表层厚度一般不一致，因此大气底层危化品浓度增加为：
在一个实施例中，溶解-挥发型危化品模型构建完成后，将该模型嵌入到大气-海洋耦合模式系统中，具体流程如下：In one embodiment, after the dissolved-volatile hazardous chemicals model is constructed, the model is embedded into the atmosphere-ocean coupled model system. The specific process is as follows:

步骤六、在ROMS模式tracer_oc的计算程序中，对表层的tracer_oc增加挥发衰减项，随着时间步长增加，海洋表层的tracer_oc不断衰减；Step 6: In the calculation program of tracer_oc in the ROMS mode, a volatile attenuation term is added to the tracer_oc of the surface layer. As the time step increases, the tracer_oc of the ocean surface layer decays continuously.
步骤七、在MCT耦合器中，将ROMS模式中表层的tracer_oc挥发的量传递给ctracer变量；Step 7: In the MCT coupler, transfer the amount of tracer_oc volatilized from the surface in the ROMS mode to the ctracer variable;
步骤八、在WRF模式的tracer_atm计算模块中，对最底层的tracer_atm，每一个时间步长计算时，从耦合器中读入ctracer变量，令tracer_atm＝tracer_atm+ctracer，实现海洋表层挥发的危化品进入到大气底层危化品的计算；Step 8. In the tracer_atm calculation module of the WRF mode, for the bottom layer tracer_atm, when calculating each time step, read the ctracer variable from the coupler, set tracer_atm = tracer_atm + ctracer, and calculate the hazardous chemicals volatilized from the ocean surface and entering the bottom layer of the atmosphere;
步骤九、在WRF模式中增加输出项：tracer_atm和ctracer。Step 9. Add output items in WRF mode: tracer_atm and ctracer.
在一个实施例中，还包括，在代码移植完毕后，模式耦合计算过程实现了溶解-挥发型危化品入海后，溶解以三维运动形式在海洋内部输移和扩散，而海洋表层的危化品以一定的速率挥发，导致表层的危化品浓度衰减，而挥发的危化品则进入到大气底层中，以三维运动形式在大气中输移和扩散。In one embodiment, it also includes that after the code is transplanted, the mode coupling calculation process realizes that after the dissolved-volatile hazardous chemicals enter the sea, they are dissolved, transported and diffused in the ocean in the form of three-dimensional motion, while the hazardous chemicals on the surface of the ocean volatilize at a certain rate, causing the concentration of hazardous chemicals on the surface to decay, and the volatilized hazardous chemicals enter the bottom layer of the atmosphere, and are transported and diffused in the atmosphere in the form of three-dimensional motion.

结合上述的所有技术方案，本发明所具备的优点及积极效果为：Combining all the above technical solutions, the advantages and positive effects of the present invention are as follows:
目前针对海上危化品泄漏的模拟预测，模拟的情景比较有限，只能针对单一类型(漂移型、悬浮型、溶解型和挥发型)的危化品泄漏事件开展模拟预测，都是单独采用海洋模式开展漂移型、悬浮型和溶解型危化品泄漏的数值模拟工作，或者单独采用大气模式开展易挥发性危化品的数值模拟工作。而真实的危化品泄漏事件中，危化品存在多种属性，如液氨，凝析油等危化品属于溶解型危化品，溶于海水在海流的作用下输移扩散，但同时在海表也易挥发进入大气中，在大气中扩散。单一的大气危化品泄漏模拟和海洋危化品模拟，只能模拟危化品泄漏后在大气或者海洋中的输移扩散，无法考虑危化品在海洋中输移过程中持续向大气挥发的过程，即对大气危化品模拟而言，存在一个持续动态移动的泄漏面源。因此需要考虑复合型危化品泄漏入海后，在海洋中和大气中的共同输移扩散。本发明构建了一种溶解-挥发型危化品的泄漏扩散模型，该类型危化品发生泄漏入海后，快速溶于海水，以三维运动形式在海洋内部输移和扩散，而海洋表层的危化品以一定的速率挥发进入到大气中，进而在大气中输移和扩散。进一步，将该模型嵌入到大气-海洋耦合模式系统中，并进行了理想案例模拟，实现溶解-挥发型危化品泄漏后在海洋和大气中的输移和扩散的数值模拟。本模型主要针对危化品入海后漂移扩散，同时又挥发进入大气中的工况，具有较好的创新性和实际应用价值，对于评估溶解-挥发型危化品泄漏入海后对海洋环境和大气环境影响有着更准确的过程刻画。At present, the simulation and prediction of hazardous chemical leakage at sea is limited in the simulation scenarios. It can only simulate and predict a single type of hazardous chemical leakage (drifting, suspended, dissolved and volatile). The numerical simulation of drifting, suspended and dissolved hazardous chemical leakage is carried out by ocean mode alone, or the numerical simulation of volatile hazardous chemicals is carried out by atmospheric mode alone. In real hazardous chemical leakage events, hazardous chemicals have multiple properties. For example, liquid ammonia, condensate oil and other hazardous chemicals belong to dissolved hazardous chemicals. They are dissolved in seawater and transported and diffused under the action of ocean currents, but at the same time, they are also easily volatilized into the atmosphere and diffused in the atmosphere on the sea surface. Single atmospheric hazardous chemical leakage simulation and marine hazardous chemical simulation can only simulate the transport and diffusion of hazardous chemicals in the atmosphere or ocean after leakage. It is impossible to consider the process of continuous volatilization of hazardous chemicals into the atmosphere during the transport process in the ocean. That is, for atmospheric hazardous chemical simulation, there is a continuously dynamically moving leakage surface source. Therefore, it is necessary to consider the joint transport and diffusion of composite hazardous chemicals in the ocean and the atmosphere after leakage into the sea. The present invention constructs a leakage and diffusion model of dissolved-volatile hazardous chemicals. After this type of hazardous chemicals leaks into the sea, they quickly dissolve in seawater and are transported and diffused in the ocean in a three-dimensional motion form, while the hazardous chemicals on the surface of the ocean evaporate into the atmosphere at a certain rate, and then are transported and diffused in the atmosphere.

本发明构建了一种易溶解和挥发的危化品泄漏扩散模型的构建方法，易溶解和挥发的危化品发生泄漏入海后，快速溶于海水，以三维运动形式在海洋内部输移和扩散，海洋表层的危化品以一定的速率挥发进入到大气中，进而在大气中输移和扩散。将该模型嵌入到大气-海洋耦合模式系统中，实现溶解-挥发型危化品泄漏后在海洋和大气中的输移和扩散的数值模拟，模拟的结果主要包括危化品泄漏后在海洋中和大气中的三维浓度分布和时间变化。The present invention constructs a method for constructing a leakage and diffusion model of easily soluble and volatile hazardous chemicals. After the easily soluble and volatile hazardous chemicals leak into the sea, they quickly dissolve in seawater, and are transported and diffused in the ocean in a three-dimensional motion form. The hazardous chemicals on the surface of the ocean volatilize into the atmosphere at a certain rate, and then transport and diffuse in the atmosphere. The model is embedded in the atmosphere-ocean coupling model system to realize the numerical simulation of the transport and diffusion of soluble-volatile hazardous chemicals in the ocean and atmosphere after leakage. The simulation results mainly include the three-dimensional concentration distribution and time variation in the ocean and atmosphere after the leakage of hazardous chemicals.
如图1所示，危化品在海洋中发生泄漏，入海后，快速溶于海水，以三维运动形式在海洋内部输移和扩散，海洋表层的危化品以一定的速率挥发，导致表层的危化品浓度衰减，而挥发的危化品则进入到大气底层中，进而在大气中三维输移和扩散。该溶解-挥发型危化品的三维扩散方程为：As shown in Figure 1, hazardous chemicals leak into the ocean and quickly dissolve in seawater after entering the sea. They are transported and diffused in the ocean in a three-dimensional form. Hazardous chemicals on the surface of the ocean evaporate at a certain rate, causing the concentration of hazardous chemicals on the surface to decay. The volatilized hazardous chemicals enter the bottom layer of the atmosphere and then transport and diffuse in the atmosphere in three dimensions. The three-dimensional diffusion equation of the dissolved-volatile hazardous chemicals is:
1、海洋表层：1. Ocean surface:
其中t为时间；x、y、z空间位置坐标；u、v、w为x、y、z方向的流速分量(m/s)；Kx为x方向的涡动扩散系数(m2/s)；Ky为y方向的涡动扩散系数(m2/s)；Kz为z方向的涡动扩散系数(m2/s)；vθ为分子扩散系数(m2/s)；C为水体中污染物的浓度(g/m3)；FC为污染物的源强(g/m3·s)，DC为污染物的耗散项(g/m3·s)，减少的VC1为海洋表层危化品挥发导致的浓度降低(volatilization作用，单位为g/m3·s)Where t is time; x, y, z are spatial position coordinates; u, v, w are flow velocity components in the x, y, z directions (m/s); Kx is the eddy diffusion coefficient in the x direction (m 2 /s); Ky is the eddy diffusion coefficient in the y direction (m 2 /s); Kz is the eddy diffusion coefficient in the z direction (m 2 /s); vθ is the molecular diffusion coefficient (m 2 /s); C is the concentration of pollutants in the water body (g/m 3 ); F C is the source intensity of the pollutant (g/m 3 ·s), D C is the dissipation term of the pollutant (g/m 3 ·s), and the reduced V C1 is the concentration reduction caused by the volatilization of hazardous chemicals in the surface layer of the ocean (volatilization effect, unit is g/m 3 ·s)
2、大气底层：2. Bottom layer of atmosphere:
增加的VC2为海洋的挥发的危化品进入大气中导致危化品浓度增加(单位为g/m3·s)Increased VC2 refers to the volatile hazardous chemicals in the ocean entering the atmosphere, resulting in an increase in the concentration of hazardous chemicals (in g/m 3 ·s)
3、海洋下层：3. Lower ocean layer:
4、大气上层：4. Upper atmosphere:
其中海洋表层危化品挥发量的计算参考半衰期浓度计算公式，假设t时刻，海洋表层的危化品浓度为Ct，危化品挥发的半衰期为T，则t+dt时刻(dt为计算时间步长)，海洋表层的危化品浓度为
图2给出了理想的溶解-挥发型危化品蒸发量和残余量时间变化曲线图，半衰期设定为12小时，时间计算步长为1分钟，计算时间为120个小时，初始浓度设定为100。Figure 2 shows the ideal time variation curve of evaporation and residual amount of dissolved-volatile hazardous chemicals. The half-life is set to 12 hours, the time calculation step is 1 minute, the calculation time is 120 hours, and the initial concentration is set to 100.
溶解-挥发型危化品模型构建完成后，将该模型嵌入到大气-海洋耦合模式系统(COAWST模式，由WRF大气模式和ROMS海洋模式构成)中，具体流程如下：After the dissolved-volatile hazardous chemicals model is built, the model is embedded in the atmosphere-ocean coupled model system (COAWST model, composed of the WRF atmospheric model and the ROMS ocean model). The specific process is as follows:
S101、在WRF模式中启用passive tracer模块选项；S101. Enable the passive tracer module option in WRF mode;
S102、在WRF模式中增加污染物变量(定义为tracer_atm)；S102. Add pollutant variable (defined as tracer_atm) in WRF mode;
S103、在WRF模式中增加海洋表层污染物蒸发变量(定义为ctracer)；S103. Add ocean surface pollutant evaporation variables (defined as ctracer) to the WRF model;

S106、在ROMS模式中tracer_oc的计算程序中，对表层的tracer_oc增加挥发衰减项，随着时间步长增加，海洋表层的tracer_oc不断衰减；S106. In the calculation procedure of tracer_oc in the ROMS mode, a volatile attenuation term is added to the tracer_oc of the surface layer. As the time step increases, the tracer_oc of the ocean surface layer continuously decays.
S107、在MCT耦合器中，将ROMS模式中表层的tracer_oc挥发的量传递给ctracer变量；S107, in the MCT coupler, the amount of tracer_oc volatilized from the surface layer in the ROMS mode is transferred to the ctracer variable;
S108、在WRF模式中的tracer_atm计算模块中，对最底层的tracer_atm，每一个时间步长计算时，从耦合器中读入ctracer变量，令tracer_atm＝tracer_atm+ctracer。实现海洋表层挥发的危化品进入到大气底层危化品的计算。S108. In the tracer_atm calculation module in the WRF mode, for the bottom layer tracer_atm, when calculating each time step, the ctracer variable is read from the coupler, and tracer_atm=tracer_atm+ctracer is set to realize the calculation of hazardous chemicals volatilized from the ocean surface and entering the bottom layer of the atmosphere.
S109、在WRF模式中增加输出项：tracer_atm和ctracer。S109. Add output items in WRF mode: tracer_atm and ctracer.
代码移植完毕后，模式耦合计算过程实现了溶解-挥发型危化品入海后，迅速溶解以三维运动形式在海洋内部输移和扩散，而海洋表层的危化品以一定的速率挥发，导致表层的危化品浓度衰减，而挥发的危化品则进入到大气底层中，以三维运动形式在大气中输移和扩散。After the code was ported, the model coupling calculation process realized that after dissolved-volatile hazardous chemicals entered the sea, they quickly dissolved and were transported and diffused in the ocean in the form of three-dimensional motion, while the hazardous chemicals on the surface of the ocean volatilized at a certain rate, causing the concentration of hazardous chemicals on the surface to decay, and the volatilized hazardous chemicals entered the bottom layer of the atmosphere and were transported and diffused in the atmosphere in the form of three-dimensional motion.
案例模拟：Case simulation:
溶解-挥发型危化品植入到大气-海洋耦合模式后，为测试模型模拟效果，开展了理想案例模拟，假设在中国台湾省以东黑潮区域发生溶解-挥发型危化品泄漏事件，选定危化品释放位置，从表到底均匀释放，初始浓度为100，模拟时间为2018年1月1日，模拟时间为9天。After the dissolved-volatile hazardous chemicals were implanted into the atmosphere-ocean coupling model, an ideal case simulation was carried out to test the model simulation effect. It was assumed that a dissolved-volatile hazardous chemical leakage incident occurred in the Kuroshio area east of Taiwan Province, China. The hazardous chemicals release location was selected and released evenly from the surface to the bottom. The initial concentration was 100, the simulation time was January 1, 2018, and the simulation time was 9 days.
根据模拟的溶解-挥发型危化品泄漏后不同时刻在海洋模式表层和大气模式底层的浓度分布，危化品泄漏后，海洋表层给的危化品随着黑潮的流动向东北方向扩展，由于在海洋中的溶解扩散和表层的挥发，浓度不断降低，第192个小时的海洋表层危化品的分布刻画了黑潮流轴。模拟得知，海洋表层的危化品在随海流漂移的过程中，持续挥发进入大气底层，进而在大气中漂移扩散，并且随着风场的变化，危化品向不同方向漂移扩散，如模拟的第24小时，挥发进入到大气中的污染物先向西漂移到中国台湾省东北，然后再转向西南；到第48小时，则之前漂移到中国台湾省南部的危化品向西北漂移，进入到广东省上方；到第96小时，风向转为西北，因此海洋表层危化品主要向西北漂移，之前挥发的危化品此时已经浓度降至较低，到第192小时时，此时海洋表层的危化品沿黑潮主轴分布，由于此时为西北风，因此挥发的危化品主要沿着黑潮主轴向西南漂移扩散。According to the simulated concentration distribution of dissolved-volatile hazardous chemicals at the surface of the ocean model and the bottom of the atmosphere model at different times after the leakage of hazardous chemicals, after the leakage of hazardous chemicals, the hazardous chemicals on the surface of the ocean expanded to the northeast with the flow of the Kuroshio Current. Due to the dissolved diffusion in the ocean and the volatilization of the surface, the concentration continued to decrease. The distribution of hazardous chemicals on the surface of the ocean at the 192nd hour portrayed the Kuroshio Current axis. The simulation shows that hazardous chemicals on the ocean surface continue to evaporate into the bottom layer of the atmosphere as they drift with the ocean currents, and then drift and diffuse in the atmosphere. As the wind field changes, the hazardous chemicals drift and diffuse in different directions. For example, in the 24th hour of the simulation, the pollutants that evaporated into the atmosphere first drifted westward to the northeast of Taiwan Province, China, and then turned to the southwest; by the 48th hour, the hazardous chemicals that had previously drifted to the southern part of Taiwan Province, China drifted northwest and entered above Guangdong Province; by the 96th hour, the wind direction turned to northwest, so the hazardous chemicals on the ocean surface mainly drifted northwest, and the concentration of the hazardous chemicals that had evaporated previously had dropped to a lower level at this time. By the 192nd hour, the hazardous chemicals on the ocean surface were distributed along the main axis of the Kuroshio. Due to the northwest wind at this time, the volatilized hazardous chemicals mainly drifted and diffused southwestward along the main axis of the Kuroshio.
