Abstract

In this work, a methodological framework is presented to automate the Lifting Condensation Level (LCL) height estimate process in meteorological applications, by assimilating dependencies on the saturation mixing ratio from a Skew-T log-P chart. Results of the methodology implementation show a high correlation with the measurements made by atmospheric soundings. In addition, LCL height maps were built for the Caribbean region, these were generated by the proposed automatized process using daily reanalysis data from 1948 to 2010.
