【摘要】 2012年美国航天航空局戈达德飞行中心(GSFC/NASA)利用热带测雨卫星(TRMM)的微波成像仪(TMI)探测结果,结合云模式计算反演,给出了新版潜热廓线资料(第七版2A12),其水平分辨率约5km,自地表至18km垂直分28层。该资料是否能有效地用于研究云和降水的潜热结构尚需检验。潜热为不可直接观测的物理量,因此不能直接检验其正确与否。为此,本文将2A12资料与TRMM的可见光/红外扫描仪(VIRS)探测结果(1B01)相融合,从而得到逐条潜热廓线相应的云顶部可见光反射率和红外辐射温度的集成资料,利用VIRS的远红外对云顶高度的指示,通过分析西北太平洋成熟台风云系的冷云、水云等相应的云水、云冰和潜热的垂直结构特点,借此检验潜热廓线的合理性。结果表明2A12资料反演的潜热廓线在降水冰云中的"合理比例"超过70%,降水暖云误判为冰云的比例约为40%。更多还原

【Abstract】 In 2012,the new version latent heat product(2 A12-v7),which use the scheme combined the observation from detection of Tropical Rainfall Measuring Mission(TRMM) Microwave Imager(TMI) and cloud resolving model(CRM),was released by Goddard Space Flight Center/National Aeronautics and Space Administration(GSFC/NASA).The horizontal resolution of the 2 A12-v7 is about 5 km.From surface to 18 km height it is divided into 28 layers.It should be examined that the products are valid for latent heat vertical structure in cloud and precipitation research.For latent heat is the physical quantity that can be observed directly,it is difficult to examine directly.Therefore,the 2 A12 data is merged with TRMM visible/infrared scanner(VIRS) results(1 B01),the rationality of the latent heat profiles from mature typhoon in Pacific Northwest is examined by using the 1 B01 data which could indicate the cloud top height.The results show that the "reasonable proportion" of latent heat profile of 2 A12 data in precipitation ice clouds is more than 70%,the "reasonable proportion" of precipitation warm clouds which misjudged to ice clouds is about 40%.更多还原
