Description

Novel tipping bucket Weighing type sleet measuring method and device
Technical field:
The present invention relates to a kind of precipitation observation technology, more particularly to a kind of novel tipping bucket Weighing type sleet measuring method and Device.
Background technology:
Precipitation measurement is one of the important content of the hydrology, weather monitoring.According to《Precipitation observation criteria》, precipitation discharge observation will expire Sufficient code requirement.In its natural state, precipitation includes rain, snow, hail etc., and rain, snow are most common dewatering modes, therefore can Accurate surveying rainfall, but the device of energy accurate surveying snowfall is particularly significant to precipitation measurement.
Currently, the device that can only observe rainfall is very ripe, and can observe rainfall can observe the device of snowfall There are no be used widely.This is to should be the shortcomings that these devices have itself.The sleet rainfall gauge weighed merely, is not arranged Water installations, long term monitoring add up precipitation, and accuracy of observation can be impacted by not only evaporating, but also manual intervention is needed to drain. Snow melt tipping bucket type rain-snow gauge also has disadvantage, first, heating initial time is difficult to judge, causes time delay;Second is that heating temperature is difficult It is excessively high in selection, cause rain gage bucket to form air column, evaporation is excessive, and influences snowflake and fall into cylinder, causes monitoring error, or Person's heating temperature is low, and snowfall cannot melt in time.In addition, weigh type rain-snow gauge and heating snow melt tipping bucket type rain-snow gauge, cannot Carry out the monitoring of merging into nature under natural conditions.
Invention content:
The technical problem to be solved by the present invention is to:It overcomes the deficiencies of the prior art and provide a kind of reasonable design, can complete to drop Rain, sleet mixing precipitation, snowfall and natural merging into nature monitoring, meet the novel tipping bucket Weighing type sleet of measurement accuracy requirement Measuring method and device.
