In the wake of eastern United States cyclone 12–14 March 1993, a cold surge, originating over Alaska and western Canada, brought northerlies exceeding 20 m s−1 temperature decreases up to 15°C 24 h into Mexico Central America. This paper addresses multiscale aspects surge from planetary scale mesoscale, focusing on 1) structure evolution leading edge 2) reasons for its extraordinary intensity equatorward extent, 3) impact Tropics, specifically, strength trade winds sea surface in Pacific....
Abstract Composite structures of African easterly waves (AEWs) that develop into named tropical cyclones in the Atlantic are compared and contrasted with nondeveloping AEWs using 40-yr ECMWF Re-Analysis (ERA-40) data satellite brightness temperature between 1979 2001. Developing characterized by a more distinctive cold-core structure two days before reaching West coast. As they move westward, convective activity increases further vicinity Guinea Highlands region. At same time AEW trough its...
The incipient stages of the 12–14 March 1993 “superstorm” (SS93) cyclogenesis over Gulf Mexico are examined. Noteworthy aspects SS93 include 1) it is deepest extratropical cyclone ever observed during 1957–96 period, and 2) existing operational prediction models performed poorly in simulating northwestern Mexico. A dynamic-tropopause (DT) analysis shows that triggered by a potent potential vorticity (PV) anomaly as crosses extreme northern approaches low-level environment western warmed,...
The results of a multiscale analysis the 12–14 March 1993 superstonn (SS93) over eastern North America are presented. A time sequence overlapping 10-day time-mean 5OO-hPa geopotential height and anomaly composites shows that Northern Hemisphere (NH) flow pattern from 18 February to 15 is characterized by 1) three persistent troughs situated Asia northwestern Pacific, America, Africa southwestern Europe eastward central Russia; 2) massive blocking anticyclone located Atlantic. Beginning 8–9...
It blew our minds."-chriStina hulBe of the University Otago in New Zealand, on discovery last December that underside Ross Ice Shelf off coast West Antarctica was layered with flat ice crystals.Melting shelves normally have smooth undersides, so presence crystals indicated seawater is actually freezing at shelf's base.Hulbe co-led a team melted two holes all way through and lowered cameras other instruments more than 1,100 feet down to waters below.Contrary their expectations, scientists...
Project Pythia is the educational arm of Pangeo community, and provides a growing collection community driven developed training resources that help geoscientists navigate ecosystem, myriad complex technologies essential for today’s Big Data science challenges. began in 2020 with support U.S. NSF EarthCube award. Much initial effort focused on Foundations: Jupyter Notebooks covered topics such as Python language basics; managing projects GitHub; authoring using...

The Eighth Cyclone Workshop was held at the Far Hills Inn and Conference Center in Val Morin, Quebec, Canada, 12–16 October 1992. workshop arranged around several scientific themes of current research interest. most widely debated theme applicability “potential vorticity thinking” to theoretical, observational, numerical studies life cycle cyclones interaction these with their environment on all spatial temporal scales. A combination invited contributed talks, preference given younger...
Abstract Florida annually leads the United States in lightning-caused fatalities. While many studies have examined lightning frequency maximum near Cape Canaveral, relatively little attention has been paid to western peninsula, which features a similar warm-season event density. Of particular concern are first cloud-to-ground (FCG) events developing thunderstorms, difficult predict with sufficient lead time and can catch people off guard. This study performs an environmental analysis of...
