Climatic Diagnosis and Analysis on The Change of Precipitation During Spring Sowing of Guangxi
摘要
Abstract
The precipitation of Guangxi during spring sowing (Feb. ～ April) and in each month from 1959 to 2000 is decomposed by way of EOF to analyze its spatial distribution conformation and the climatic variation law. The results shows that the commonly more (less) precipitation during spring sowing and in each month is the main spatial distribution conformation. Precipitation in Feb. and in March tends to increase, and that in April tends to decrease on the contrary. Quasi-2-year oscillation exists in the precipitation in each month and during spring sowing, and precipitation in each month complies with a long periodically changing law of about 45 years. In the late 1990s, precipitation in spring sowing of Guangxi enters its cycle of less raining.关键词
