DOI: 10.1002/2016gl071542
Abstract: To better represent organized convection in the Climate Forecast System version 2 (CFSv2), a stochastic multicloud model (SMCM) parameterization is adopted and a 15 year climate run is made. The last 10 years of simulations are analyzed… read more here.

DOI: 10.1002/2016jd026158
Abstract: An evaluation-classification-downscaling-based climate projection (ECDoCP) framework is developed to fill a methodological gap of general circulation models (GCMs)-driven statistical-downscaling-based climate projections. ECDoCP includes four interconnected modules: GCM evaluation, climate classification, statistical downscaling, and climate projection.… read more here.

DOI: 10.1002/2016jd026282
Abstract: The Andes-Amazon transition, along the eastern Peruvian Andes, features “hotspots” with strong precipitation. Using 15 years of TRMM PR data we established a robust relation between terrain elevation and mean surface precipitation, with the latter… read more here.
