中国地区海风(锋)的数值模拟研究进展

海风锋是海风环流前缘形成的锋面,具有类似于冷锋的特征.海风锋能触发强对流,造成沿海地区雷暴等灾害性天气,是沿海地区气象研究的重点对象.随着数值模式和计算机技术的发展,数值模拟已成为气象研究中的重要方法.因此,海风(锋)的数值模拟受到越来越多的关注.过去的40年中,中国地区海风(锋)的数值研究不断开展,取得了不少研究成果.为了加深对海风(锋)数值模拟的认识,了解最新研究成果,本文对中国地区海风(锋)数值模拟进行了概述,重点讨论了海风三维结构与演变以及背景风、地形、城市热岛和大气稳定度对海风(锋)的影响.此外,本文也归纳总结了模式物理过程参数化对海风(锋)模拟的影响以及海风(锋)的大涡模拟研究.最后,对一些需要进一步研究的问题提出了建议.

An overview of numerical studies of sea breeze front in China

Sea Breeze Front (SBF) is the landward edge of sea breeze circulation,which has similar characteristics to the cold front.SBF has always been a key object of coastal meteorological research since it can trigger strong convection even disastrous weather such as thunderstorms in coastal areas.Numerical simulation has become an important tool in meteorological research with the rapid development of numerical models and computer technology.The numerical simulation of SBF has attracted much attention and yielded fruitful results.Here,we summarize the numerical simulation of SBF carried out in China in the past 40 years,and detail on the effects of environmental flow,topography,urban heat island and atmosphere stability on SBF.In addition,the influence of physical parameterization on SBF and the work of large eddy simulation are summarized.Finally,we sum up some issues which are needed to be addressed for further study.
