Meteorological climate regionalization argument and cause

Abstract

The invention provides meteorological climate regionalization arguments and causes by using the historical data of meteorological observation sites of the regionalization since building, comparing and analyzing and researching the temperature, precipitation, wind, sand and sunlight and other meteorological elements while combining with the annual, seasonal and monthly and other characteristics according to the anomalism of the climate, and researching the generation and distribution rules of meteorological climate regionalization from the time and space, wherein the generation and distribution rules comprise interannual change, annual change, seasonal change and abnormal change. The relation of the meteorological climate regionalization and EL-Nino events, NAO (North Atlantic Oscillation), PDO (Pacific Decadal Oscillation), SOI (Southern Oscillation Index), AO (Angola) and other factors by means of teleconnection analysis is indicated, and the characteristics of atmospheric circulation anomalies which cause the climate regionalization anomalies are indicated.

Description

technical field [0001] The invention belongs to the field of meteorology, and in particular relates to the demonstration and causes of meteorological and climate divisions. Background technique [0002] Meteorological and climate regionalization is based on the similarity and difference of climate characteristics, with certain indicators, to divide the climate region of a certain area. The climate of the region is divided step by step, and the places with roughly the same climate are divided into one area, and the places with different climates are divided into another area, that is, several levels of divisional units are obtained. Regionalization demonstration and its causes have played an important role in agricultural meteorological services such as agricultural planting structure and variety zoning, crop growth monitoring and grain yield forecasting, forest fire monitoring and meteorological condition forecasting. At present, the commonly used indicators in my country's...
