RISMixed Rossby–Gravity Waves Triggered by Lateral Forcing
Publisher: American Meteorological Society
Abstract: The mechanisms associated with the excitation of mixed Rossby-gravity waves (MRGWs) in the upper troposphere are studied using wind and outgoing longwave radiation (OLR) data from 1979 to 1991. The largest anomalies in ...
Regional Aspects of Prolonged Meteorological Droughts over Mexico and Central America
Publisher: American Meteorological Society
Abstract: Major prolonged droughts in Mexico during the twentieth century are mainly related to anomalous dry summers, such as those observed in the 1930s, the 1950s, or the 1990s. Droughts in northern Mexico frequently coincide ...
Tropical-Midlatitude Interaction on the Time Scale of 30 to 60 Days during the Northern Summer of 1979
Publisher: American Meteorological Society
Abstract: The relationship between the low-frequency oscillation of convective activity in the tropics and the intensity of planetary-scale upper-tropospheric (200 mb) systems in the subtropics during the Northern Hemisphere (NH) ...
Estimation of Vulnerability and Risk to Meteorological Drought in Mexico
Publisher: American Meteorological Society
Abstract: rolonged droughts severely affect the economic, social, and environmental sectors in Mexico. The interest in reducing the costs of drought is now focused on prevention by means of vulnerability reduction. The present study ...
The Midsummer Drought over Mexico and Central America
Publisher: American Meteorological Society
Abstract: The annual cycle of precipitation over the southern part of Mexico and Central America exhibits a bimodal distribution with maxima during June and September?October and a relative minimum during July and August, known as ...
Michio Yanai and Tropical Waves
Publisher: American Meteorological Society
Abstract: nsights by Professor Michio Yanai on tropical waves, which have been vital ingredients for progress in tropical meteorology over the last half-century, are recollected. This study revisits various aspects of research on ...
Operational Hazard Assessment of Waves and Storm Surges from Tropical Cyclones in Mexico
Publisher: American Meteorological Society
Abstract: ropical cyclones and their associated impacts along the western and eastern Mexican coastlines have led to the recent announcement of the creation of a National Hurricane and Severe Storms Center in Mexico. While Mexico ...
A U.S. CLIVAR Project to Assess and Compare the Responses of Global Climate Models to Drought-Related SST Forcing Patterns: Overview and Results
Publisher: American Meteorological Society
Abstract: The U.S. Climate Variability and Predictability (CLIVAR) working group on drought recently initiated a series of global climate model simulations forced with idealized SST anomaly patterns, designed to address a number of ...
The NAME 2004 Field Campaign and Modeling Strategy
Publisher: American Meteorological Society
Abstract: The North American Monsoon Experiment (NAME) is an internationally coordinated process study aimed at determining the sources and limits of predictability of warm-season precipitation over North America. The scientific ...
