  journal={Monthly Weather Review},
In the wake of the eastern United States cyclone of 12‐14 March 1993, a cold surge, originating over Alaska and western Canada, brought northerlies exceeding 20 m s21 and temperature decreases up to 158C over 24 h into Mexico and Central America. This paper addresses the multiscale aspects of the surge from the planetary scale to the mesoscale, focusing on 1) the structure and evolution of the leading edge of the cold surge, 2) the reasons for its extraordinary intensity and equatorward extent… Expand
The Structure and Evolution of Gap Outflow over the Gulf of Tehuantepec, Mexico
Abstract Mesoscale-model simulations are used to examine the structure and dynamics of a gap-outflow event over the Gulf of Tehuantepec, Mexico, that was associated with a surge of cold air along theExpand
Cold surge activity over the Gulf of Mexico in a warmer climate1
Cold surges are a dominant feature of midlatitude tropical interaction. During the North Hemisphere (NH) winter, midlatitude waves propagating from the Rocky Mountains into the Gulf of Mexico resultExpand
Cold Surges in Tropical and Extratropical South America: The Strong Event in June 1994
The authors investigate one case of surges of polar air that occasionally propagate into southeastern Brazil during wintertime and are harmful to coffee production because of the freezing conditionsExpand
Effect of the Andes Cordillera on Precipitation from a Midlatitude Cold Front
The effects of the Andes Cordillera, the major mountain range in South America, on precipitation patterns of baroclinic systems approaching from the southeast Pacific remain largely unstudied. ThisExpand
Cold Air Incursions over Subtropical and Tropical South America: A Numerical Case Study
Abstract Synoptic-scale incursions of cold, midlatitude air that penetrate deep into the Tropics are frequently observed to the east of the Andes cordillera. These incursions are a distinctiveExpand
Subtropical cold surges: regional aspects and global distribution
Shallow surges of cold dry air are frequently observed to the east of the major mountain ranges, moving from mid-latitudes well into the Tropics in about 4 days. Because of their strong impact onExpand
Planetary- and Synoptic-Scale Signatures Associated with Central American Cold Surges
Abstract Motivated by outstanding issues from a previous case study of a midlatitude cold surge that affected Mexico and Central America, the climatology of Central American cold surges is examinedExpand
Influence of the Subtropical Andes on Baroclinic Disturbances: A Cold Front Case Study
Abstract The Andes Cordillera produces a significant disruption to the structure and evolution of the weather systems that cross South America. In particular, cold fronts tend to be “channeled” toExpand
Impact of Subgrid-Scale Orography on Equatorial Angular Momentum Budget and the Cold Surges in a General Circulation Model
AbstractThe dynamical relations between equatorial atmospheric angular momentum (EAAM), equatorial mountain torques, and cold surges are analyzed in a general circulation model (GCM). First, theExpand
Deep-Tropospheric Gravity Waves Created by Leeside Cold Fronts
Abstract The water vapor channel of the Geostationary Operational Environmental Satellite GOES-8 reveals narrow (30 km wide), elongated (500–1000 km) bands that propagate southward on the easternExpand


The Structure and Evolution of Cold Surges East of the Rocky Mountains
Abstract Northerly surges of cold air often move southward along the eastern side of the Rockies from southern Canada into Mexico. The strongest surges, which generally develop in midwinter, areExpand
Offshore wind forcing in the Gulf of Tehuantepec, Mexico: The asymmetric circulation
Since the early surveys carried out by the Eastern Tropical Pacific (EASTROPIC) and Scripps Tuna Oceanographic Research (STOR) projects in the tropical Pacific off Mexico, the northerly winds whichExpand
Northeasterly Cold Surges and Near-Equatorial Disturbances over the Winter MONEX Area During December 1974. Part II: Planetary-Scale Aspects
Abstract In Part I of this pre-winter MONEX study a synoptic analysis on the interaction between cold air surges off the East Asian continent and the synoptic-scale disturbances, especially theirExpand
Supersquirt: Dynamics of the Gulf of Tehuantepec, Mexico
T H E LAST TWO DECADES have seen a continuing effort to observe and model the response to wind forcing in the coastal ocean along eastern boundaries of ocean basins. The emphasis of research hasExpand
Rainfall distribution and regime in Central America
SummarySeasonal variations of the atmospheric circulation on the western flanks of the North Atlantic Anticyclone imply upward motion over the Caribbean Sea during the summer half-year, with aExpand
Observations and modeling of a mesoscale cold surge during WISPIT
A transient feature marked primarily by a sudden increase in wind speed and brief period of heavy snow was observed over northeastern Colorado on 11-12 March 1993. Little, if any, abrupt changes inExpand
A Windstorm in the Lee of a Gap in a Coastal Mountain Barrier
Abstract This paper describes a localized windstorm that struck some areas of northwest Washington State on 28 December 1990 with winds exceeding 45 m s−1, resulting in extensive property damage,Expand
A Synoptic Investigation of Anticyclogenesis Accompanying North American Polar Air Outbreaks
Abstract Results are presented for a synoptic-dynamic investigation of certain polar anticyclones originating in northwestern Canada.. A composite, consisting of three similar high pressure systems,Expand
Overview of the 12–14 March 1993 Superstorm
