Synoptic-Dynamic Climatology of the “Bomb”
Frederick Sanders,John R. Gyakum +1 more
TL;DR: In this article, the authors defined a bomb as an extratropical surface cyclone whose central pressure fall averages at least 1 mb h−1 for 24 hours, and studied this explosive cyclogenesis in the Northern Hemisphere during the period September 1976-May 1979.
Journal ArticleDOI
North American extreme temperature events and related large scale meteorological patterns: a review of statistical methods, dynamics, modeling, and trends
Richard Grotjahn,Robert X. Black,Ruby Leung,Michael Wehner,Mathew Barlow,Michael G. Bosilovich,Alexander Gershunov,William J. Gutowski,John R. Gyakum,Richard W. Katz,Yun-Young Lee,Young-Kwon Lim,Prabhat +12 more
TL;DR: The current state of knowledge regarding large-scale meteorological patterns (LSMPs) associated with short-duration (less than 1-week) extreme precipitation events over North America is surveyed in this article.
Journal ArticleDOI
Northern Lake Impacts on Local Seasonal Climate
TL;DR: In this article, the Canadian Regional Climate Model (CRCM) is used to simulate seasonal time scales for the Mackenzie River basin and northwest region of Canada, coupled to simulations of Great Bear and Great Slave Lakes using the Princeton Ocean Model (POM) to examine the interactions between large northern lakes and the atmosphere.
Journal ArticleDOI
The extratropical transition of tropical cyclones. Part I: Cyclone evolution and direct impacts
Clark Evans,Kimberly M. Wood,Sim D. Aberson,Heather M. Archambault,Shawn M. Milrad,Lance F. Bosart,Kristen L. Corbosiero,Christopher A. Davis,João Rafael Dias Pinto,James D. Doyle,Chris Fogarty,Thomas J. Galarneau,Christian M. Grams,Kyle S. Griffin,John R. Gyakum,Robert E. Hart,Naoko Kitabatake,Hilke S. Lentink,Ron McTaggart-Cowan,William Perrie,Julian F. Quinting,Carolyn A. Reynolds,Michael Riemer,Elizabeth A. Ritchie,Yujuan Sun,Fuqing Zhang +25 more
TL;DR: Extratropical transition (ET) is the process by which a tropical cyclone, upon encountering a baroclinic environment and reduced sea surface temperature at higher latitudes, transforms into an extraspatial cyclone.
Journal ArticleDOI
Analysis of Hurricane Catarina (2004)
Ron McTaggart-Cowan,Lance F. Bosart,Christopher A. Davis,Eyad H. Atallah,John R. Gyakum,Kerry Emanuel +5 more
TL;DR: The development of Hurricane Catarina over the western South Atlantic Ocean in March 2004 marks the first time that the existence of a hurricane has been confirmed by analysis and satellite imagery in the South Atlantic basin this paper.
