New statistics for precipitation-water vapor relationships for climate model evaluation
Abstract
Observational results will be summarized from several related approaches to analyzing precipitation dependence on tropospheric water vapor and temperature and the impacts of this in the interactions between tropical convection zones and the large scale. The following analyses based on combinations of data from Tropical Rainfall Measuring Mission, AQUA, Atmospheric Radiation Measurement program, and other sources, can contribute to model evaluation and improvement. (i) Statistics for the onset of deep convection as a function of column and free tropospheric water vapor can aid in constraining entrainment representations; (ii) a close analogy to the properties of a continuous phase transition permits the statistics for the onset of tropical strong deep convection to be collapsed in a form potentially suitable for model validation; (iii) variability at certain margins of the tropical convection zones exhibits differences based on characteristics of the inflow that may help constrain model representations of the interaction of convection with inflow air masses.
