Abstract

The invention discloses a method for determining a regional atmospheric precipitation pattern index R, belongs to the technical field of atmospheric precipitation index analysis, and can solve the problem that the existing precipitation pattern index cannot reflect the change of spatial and temporal distribution of precipitation and cannot reflect the regional air water vapor resource quantity and supply condition. The determination method comprises the following steps: obtaining rainfall data of a to-be-measured time period of a research area, and obtaining an area rainfall index M according to the rainfall data; obtaining the total water vapor transport flux Q of the whole atmosphere of a unit air column of the research area, and obtaining an area water vapor transport index T according to the total water vapor transport flux Q; and according to the regional rainfall index M and the regional water vapor transport index T, calculating to obtain a regional atmospheric rainfall pattern index R.

Description

technical field [0001] The invention relates to a method for determining a regional atmospheric precipitation pattern index, and belongs to the technical field of atmospheric precipitation index analysis. Background technique [0002] The change of regional precipitation can be regarded as two aspects: one is the change of the total amount, and the other is the water vapor supply. The change of the total amount is relatively easy to quantify. The existing research on regional precipitation is mainly on the amount of precipitation, and there are few studies on the concentration degree and concentration period of precipitation. To form precipitation in a region, sufficient water vapor supply is required. Airborne water vapor resources are a potential water resource. The content and transportation of water vapor in the atmosphere is an important part of regional precipitation, which is closely related to the regional atmospheric precipitation pattern. [0003] At present, the ...
