Agricultural meteorological disasters are disasters caused to agriculture by adverse meteorological conditions. Heat damage, freezing damage, frost damage, tropical crop cold damage and low-temperature cold damage caused by temperature factors; drought, flood, snow and hail damage caused by the moisture factor; wind damage caused by wind; the comprehensive effect of meteorological factors causes dry and hot air, cold rain, freezing and waterlogging, and the like. Unlike the concept of weather, agricultural weather disasters are combined with the disaster suffered by agricultural production. For example, cold tides, late spring coldness, etc., are weather phenomena or processes in the weather, and do not always cause disasters. However, when they endanger crops such as wheat and rice, they cause agricultural meteorological disasters such as freeze injury, frost damage and low-temperature cold injury.
For the same weather and climate phenomenon, the weather disasters are not formed for different crops in the same period, such as: waterlogging is not a meteorological disaster for aquatic crops, is not a meteorological disaster for rice in a seedling raising period, but is a waterlogging disaster for corns and wheat in a fruiting period. The early warning is carried out by simply using weather and climate phenomena, and the agricultural early warning cannot be accurately provided.
Present agricultural meteorological disaster generally can divide into two kinds of situations, one kind is comparatively audio-visual calamity, for example drought and waterlogging calamity and hail big snow etc, distinguish very easily and judge and in time take measures, another kind is comparatively concealed calamity, for example freeze injury or low temperature cold injury, this kind of calamity is comparatively concealed, interference factor is also many, the difference in temperature all can lead to crops to receive the injury at night even round the clock, this kind of calamity is difficult to perceive and takes suitable precautionary measure, not only lead to crops not good in growth vigor easily, freeze and cause certain loss even.
