摘要:

利用WRF模式6種適合高分辨率且包含多種固態(tài)水成物粒子的云微物理參數化方案，分別對2012年5月16日江蘇北部一次颮線過程進行數值試驗，結果表明：LIN方案模擬的颮線回波反射率、強降水TS評分、結構和強度等均要優(yōu)于其余5種微物理參數化方案。分析不同參數化試驗結果中不同水成物粒子占比隨時間的變化特征，并針對LIN方案采取敏感性試驗和水成物轉化微物理過程分析指出，在此次颮線過程中的各水成物粒子中，霰/雹粒子占比最大，是降水過程中最重要的粒子；地面降水直接來源是雨水，雨水主要來源于中層霰/雹粒子的融化，小部分來源于云水的自動轉化；中層霰/雹粒子最主要來源是通過雨霰轉化過程中的雨水撞凍冰雹微物理過程，其次是霰撞凍云水的微物理過程，而冰相物質雪晶和云冰的碰并、撞凍和自動轉化過程微乎其微。

Abstract:

Six cloud microphysical parameterization schemes of WRF model with high resolution and multiple moisture variables are conducted to numerically simulate a squall line in the northern Jiangsu on May 16, 2012. Results show that the echo reflectance, TS scores about heavy rain, structures and strength of the mimetic squall line simulated by LIN scheme are obviously superior to the other five cloud microphysical schemes. Moreover, the variation trend characteristics of moisture variables over time in different cloud microphysical parameterization schemes were analyzed and several sensitivity experiments in allusion to LIN scheme were carried out to clarify the microphysical transform process among different moisture variables. Experimental results show that the mixing ratio of graupel or hail is the maximum in all moisture variables and is the most important part of this squall line. Rainwater, originated mainly from the melting process of graupel and hail at the middle level and partly from cloud water, is the direct source of surface rain. The primary moisture variables, namely graupels or hails, are transformed from the conversion of raindrops to graupels or hail due to rain accretion. The accretion of drop water by graupels is the secondary contribution. As for the collection and accretion processes between cloud ice and snow as well as the autoconvertion, they are considered as negligible in the graupel and hail formation.
