冷高压,气象术语,按照静力学关系,冷高压的强度随高度减弱,到高空则转为冷低压。所以,它是一种比较浅薄的天气系统,平均厚度不超过3km。 冷高压常出现在高空槽的后下方,由于槽后的质量辐合,可使其下面的高压得以维持和加强,并受高空气流的引导而移动。在槽后西北气流的引导下,使整个高压系统南下,或分裂成几个高压而南下,其中强的高压南下可形成一次寒潮过程。
地面气压场主要受庞大的冷高压控制。
Surface pressure field was mainly controlled by the huge clod high pressure.
本文对1989~1997年冬季冷高压气压场与夏秋热带气旋发生个数进行时滞相关分析,发现,两者间隔以后滞7个月为显著正相关。
A time-delayed correlation analysis between cold high pressure in winter and the number of tropical cyclones in summer for the period of 1989~1997 has been made.
它们基本上会保持自身的状态,直到由强烈的化学物质、高压、热或冷改变特性,或者成为其他生物的食物。
They stay roughly the way they are until they are denatured by strong chemicals, high pressure, heat or cold, or by becoming food for another living thing.
