摘要:

根据“溃变理论”和V—3θ 图预报工具,制作了西北地区36 个探空站点的V—3θ 图。通过对2004 年8 月发生在青海西部、甘肃东南部和宁夏南部的一次大范围冰雹天气过程V—3θ 图综合分析,结果表明:在干旱半干旱地区,基于溃变理论的预报工具对冰雹天气具有一定的预报能力。

Abstract:

Based on the blown - up theory and the V - 3θ structural prediction method,V - 3θ figures of 36 aerological stations in Northwest China were made. The hail weather course which occurred in August,2004 in west Qinghai,southeast Gansu and south Ningxia was analyzed by the V - 3θ figures. Results show that the prediction tools based on the blown - up theory is capable of forecasting hail weather to some extent in the semiarid and arid region.

Key words: Northwest China, blown - up theory, hail weather forecast
