Abstract

The invention discloses a meteorological drought monitoring and prediction method, and belongs to the technical field of meteorological drought monitoring and prediction. The method comprises the following steps: obtaining precipitation remote sensing image data in a certain time period from an authority website; converting the remote sensing image data into precipitation; forming a monthly-scalecalculation time period by continuous 30 days, adding the precipitation of each day in the calculation time period to obtain the precipitation of the calculation time period, respectively calculatingthe precipitation of the calculation time period and the precipitation of the same period over the years, and calculating to obtain the monthly-scale precipitation mean percentage; and making a monthly-scale precipitation and mean percentage distribution diagram of the target area. According to the method, the weather conditions and the temperature ranges of all days in the future can be obtainedaccording to the weather forecast information issued by the meteorological department, the predicted precipitation mean square percentage of all days in the future is calculated, and therefore the purpose of conducting quantitative drought prediction on all days in the future is achieved.

Description

technical field [0001] The invention belongs to the technical field of meteorological drought monitoring and forecasting, in particular to a meteorological drought monitoring and forecasting method. Background technique [0002] Drought is a complex natural phenomenon that commonly occurs in the world. It affects a wide range and lasts for a long time. It is one of the most serious natural disasters in agricultural production and human life. Due to different areas of concern, drought is usually divided into 4 categories: meteorological drought: abnormal water shortage caused by the imbalance of precipitation and evaporation; agricultural drought: external environmental factors cause water shortage in crops and affect the normal growth of crops Development; hydrological drought: water shortage caused by the imbalance between precipitation and surface water or groundwater; socioeconomic drought: water shortage caused by the imbalance of water supply and demand between natural ...
