Abstract: This paper describes the tropospheric circulation over the lower deserts of Arizona, California, and northwestern Mexico using observations from a special rawinsonde network operated during July and August as part of the ...

Abstract: he prediction skill of precipitation at submonthly time scales during the boreal summer season is investigated based on hindcasts from three global ensemble prediction systems (EPSs). The results, analyzed for lead times ...

Abstract: This study examines skill of retrospective forecasts using the ECHAM4.5 atmospheric general circulation model (AGCM) forced with predicted sea surface temperatures (SSTs) from methods of varying complexity. The SST fields ...

Abstract: he performance of the International Research Institute for Climate and Society ?ENSO forecast plume? during the 2002?11 period is evaluated using deterministic and probabilistic verification measures. The plume includes ...

Abstract: model predictions of ENSO conditions during the 2002?11 period are evaluated and compared to skill levels documented in studies of the 1990s. ENSO conditions are represented by the Niño- 3.4 SST index in the east-central ...

Abstract: This paper examines the quality of seasonal probabilistic forecasts of near-global temperature and precipitation issued by the International Research Institute for Climate and Society (IRI) from late 1997 through 2008, ...

Abstract: t U.S. National Academies report, Assessment of Intraseasonal to Interannual Climate Prediction and Predictability, was unequivocal in recommending the need for the development of a North American Multimodel Ensemble (NMME) ...
