TL;DR: In this article, the origin and maintenance of the 1998 Oklahoma-Texas (OK-TX) drought were investigated using the National Centers for Environmental Prediction (NCEP) global and regional models.

TL;DR: In this paper, an alternative method (called RAN) is examined that combines model output statistics and perfect prog, while at the same time utilizing the information in reanalysis data.

TL;DR: In this article, a review of simulation studies and real-data experiments that were conducted to assess the impact of satellite observations on numerical weather prediction is presented, showing that while there has been some redundancy between observing systems, satellite data have made significant contributions toward improving global forecasting.

TL;DR: In this article, the effect of vegetation feedback on decadal-scale Sahel rainfall variability is analyzed using an ensemble of climate model simulations in which the atmospheric general circulation model ICTPAGCM (SPEEDY) is coupled to the dynamic vegetation model VEGAS to represent feedbacks from surface albedo change and evapotranspiration, forced externally by observed sea surface temperature (SST) changes.

TL;DR: In this paper, a breeding method has been implemented in the NASA Seasonal-to-Interannual Prediction Project (NSIPP) Coupled General Circulation Model (CGCM) with the goal of improving operational seasonal to interannual climate predictions through ensemble forecasting and data assimilation.
