RISThe Influence of Mesoscale Features of the Sea Surface Temperature Distribution on Marine Boundary Layer Winds off the Scotian Shelf during the Superstorm of March 1993
Publisher: American Meteorological Society
Abstract: This paper studies the mesoscale wind field during the blizzard of March 1993 off the east coast of North America and examines the influence of the sea surface temperature distribution on surface winds. Can the Gulf Stream ...
On the Use of NCEP–NCAR Reanalysis Surface Marine Wind Fields for a Long-Term North Atlantic Wave Hindcast
Publisher: American Meteorological Society
Abstract: This paper uses a state-of-the-art, third-generation wave model to evaluate the marine surface wind fields produced in the National Centers for Environmental Protection?National Center for Atmospheric Research (NCEP?NCAR) ...
Trends of Atlantic Wave Extremes as Simulated in a 40-Yr Wave Hindcast Using Kinematically Reanalyzed Wind Fields
Publisher: American Meteorological Society
Abstract: In this study, seasonal extremes of wave height in the North Atlantic are analyzed. The analysis is based on a 40-yr (1958?97) numerical wave hindcast using an intensive kinematic reanalysis of wind fields. Changes in the ...
Changes of Extreme Wave Heights in Northern Hemisphere Oceans and Related Atmospheric Circulation Regimes
Publisher: American Meteorological Society
Abstract: This study assesses trends in seasonal extremes (90- and 99-percentiles) of Significant Wave Height (SWH) in the North Atlantic and the North Pacific, as simulated in a 40-yr global wave hindcast using the National Centers ...
Homogenization and Trend Analysis of Canadian Near-Surface Wind Speeds
Publisher: American Meteorological Society
Abstract: Near-surface wind speeds recorded at 117 stations in Canada for the period from 1953 to 2006 were analyzed in this study. First, metadata and a logarithmic wind profile were used to adjust hourly wind speeds measured at ...
A Quality Assurance System for Canadian Hourly Pressure Data
Publisher: American Meteorological Society
Abstract: In this study a comprehensive quality assurance (QA) system, which includes the hydrostatic check combined with a statistical homogeneity test, is designed and applied to hourly pressure records (for 1953?2002) from 761 ...
North Atlantic Ocean Wave Climate Change Scenarios for the Twenty-First Century
Publisher: American Meteorological Society
Abstract: Using the observed relationships between sea level pressure (SLP) and significant wave height (SWH) as represented by regression models, climate change scenarios of SWH in the North Atlantic were constructed by means of ...
Observed Changes in Cyclone Activity in Canada and Their Relationships to Major Circulation Regimes
Publisher: American Meteorological Society
Abstract: This study assessed the climate and trend of cyclone activity in Canada using mainly the occurrence frequency of cyclone deepening events and deepening rates, which were derived from hourly mean sea level pressure data ...
Projection and Analysis of Extreme Wave Climate
Publisher: American Meteorological Society
Abstract: The nonhomogeneous Poisson process is used to model extreme values of the 40-yr ECMWF Re-Analysis (ERA-40) significant wave height. The parameters of the model are expressed as functions of the seasonal mean sea level ...
Climatology and Changes of Extratropical Cyclone Activity: Comparison of ERA-40 with NCEP–NCAR Reanalysis for 1958–2001
Publisher: American Meteorological Society
Abstract: In this study, a cyclone detection/tracking algorithm was used to identify cyclones from two gridded 6-hourly mean sea level pressure datasets: the 40-yr ECMWF Re-Analysis (ERA-40) and the NCEP?NCAR reanalysis (NNR) for ...
