Abstract:
LAS shows low value at night , and precipitation process often follow it.This phenomenon includes most large rain process. So low value of LAS at night is a good prelude to precipitation.
The amount of low value has clear directive meaning to rain volume. When the value
Is Larger than 7,it may not rain heavily. When the value is smaller than 7,there will be moderate rain or heavy rain. The rain usually starts from 10-34 hr after appearing the low value.
Why can low value of LAS predicting future precipitation?
A low value area of torrent exists before it rains .The formation of the district
And the formation of rain process are related to the low value, including against temperature below cloude and so on.
