东北冷涡特征及其对强对流天气影响研究进展
The review of the characteristics of Northeast China Cold Vortex and its impact on the severe convective weather
摘要
Abstract
The Northeast China Cold Vortex(NCCV)is a critical component of the East Asian monsoon system,exerting substantial influence on weather and climate patterns across the region.It usually exhibits a typical struc-ture bounded by a dynamical tropopause,characterized by a cold core in the lower levels and a warm core in the upper levels,with the tropopause often descending below 300 hPa.The cold core structure of the NCCV provides mid-tropospheric cold air conditions,while low-level warm moist air advection combined with radiative heating is conducive to the formation of favorable environment conditions for severe convective weather.Along the southeast-ern and southwestern peripheries of the NCCV,interactions between the cold vortex and low-level warm moist flows promote the formation of frontal zones and boundary-layer convergence lines,which readily trigger me-soscale convective systems.These systems produce severe convective weather,including short-duration heavy pre-cipitation,thunderstorm gale,hail,and tornadoes.Compared to non-NCCV circulation patterns,severe convective environments under NCCV conditions are typically associated with steeper temperature lapse rates,significantly lower low-level moisture content,shallower moist layers,and stronger vertical wind shear.This paper systematically reviews and summarizes advances in research on the characteristics of the NCCV and its impacts on severe convec-tive weather,including formation mechanisms,spatiotemporal variations,structural features,and associated convec-tive phenomena.Furthermore,it discusses existing challenges and potential perspectives for future research,aiming to provide insights for both in-depth study and operational forecasting of NCCV-induced severe convective weather.关键词
