RISSensitivity of Atlantic Tropical Storm Frequency to ENSO and Interdecadal Variability of SSTs in an Ensemble of AGCM Integrations
Publisher: American Meteorological Society
Abstract: A significant reduction (increase) of tropical storm activity over the Atlantic basin is observed during El Niño (La Niña) events. Furthermore, the number of Atlantic tropical storms displays an interdecadal variability ...
Impact of Large-Scale Circulation on Tropical Storm Frequency, Intensity, and Location, Simulated by an Ensemble of GCM Integrations
Publisher: American Meteorological Society
Abstract: Tropical storms simulated by a nine-member ensemble of GCM integrations forced by observed SSTs have been tracked by an objective procedure for the period 1980?88. Statistics on tropical storm frequency, intensity, and ...
Simulation of Interannual Variability of Tropical Storm Frequency in an Ensemble of GCM Integrations
Publisher: American Meteorological Society
Abstract: The present study examines the simulation of the number of tropical storms produced in GCM integrations with a prescribed SST. A 9-member ensemble of 10-yr integrations (1979?88) of a T42 atmospheric model forced by observed ...
A Framework for Assessing Operational Madden–Julian Oscillation Forecasts: A CLIVAR MJO Working Group Project
Publisher: American Meteorological Society
Abstract: The U.S. Climate Variability and Predictability (CLIVAR) MJO Working Group (MJOWG) has taken steps to promote the adoption of a uniform diagnostic and set of skill metrics for analyzing and assessing dynamical forecasts ...

The Second Phase of the Global Land–Atmosphere Coupling Experiment: Soil Moisture Contributions to Subseasonal Forecast Skill
Publisher: American Meteorological Society
Abstract: he second phase of the Global Land?Atmosphere Coupling Experiment (GLACE-2) is a multi-institutional numerical modeling experiment focused on quantifying, for boreal summer, the subseasonal (out to two months) forecast ...
ECMWF Activities for Improved Hurricane Forecasts
Publisher: American Meteorological Society
Abstract: AbstractTropical cyclones are some of the most devastating natural hazards and the ?three beasts??Harvey, Irma, and Maria?during the Atlantic hurricane season 2017 are recent examples. The European Centre for Medium-Range ...
The Subseasonal to Seasonal (S2S) Prediction Project Database
Publisher: American Meteorological Society
Abstract: emands are growing rapidly in the operational prediction and applications communities for forecasts that fill the gap between medium-range weather and long-range or seasonal forecasts. Based on the potential for improved ...
