Detection of cloud vertical structure using water vapor pressure in tropical region

Abstract

A new method is proposed in this paper to determine the cloud vertical structure using water vapor pressure estimated from radiosonde profile. The presence of a cloud depends on the following criteria: the measured water vapor pressure being larger than the critical water vapor pressure at the same level. The estimated results of cloud vertical structures using the proposed method are compared with the Salonen and Uppala model and ceilometer (CL31) data. Results show good agreement between the proposed model, the existing model and the measured data.
