RISSpatial–Intensity Variations in Extreme Precipitation in the Contiguous United States and the Madden–Julian Oscillation
Publisher: American Meteorological Society
Abstract: he spatial?intensity variability of extreme precipitation over the contiguous United States (CONUS) during boreal winter and relationships with the Madden?Julian oscillation (MJO) are investigated. Daily gridded precipitation ...
Climate Change in the South American Monsoon System: Present Climate and CMIP5 Projections
Publisher: American Meteorological Society
Abstract: he South American monsoon system (SAMS) is the most important climatic feature in South America. This study focuses on the large-scale characteristics of the SAMS: seasonal amplitudes, onset and demise dates, and durations. ...
CMIP5 Simulations of Low-Level Tropospheric Temperature and Moisture over the Tropical Americas
Publisher: American Meteorological Society
Abstract: lobal warming has been linked to systematic changes in North and South America's climates and may severely impact the North American monsoon system (NAMS) and South American monsoon system (SAMS). This study examines ...
A Satellite Method to Identify Structural Properties of Mesoscale Convective Systems Based on the Maximum Spatial Correlation Tracking Technique (MASCOTTE)
Publisher: American Meteorological Society
Abstract: A simple, fully automated, and efficient method to determine the structural properties and evolution (tracking) of cloud shields of convective systems (CS) is described. The method, which is based on the maximum spatial ...
Active and Break Phases in the South American Monsoon System
Publisher: American Meteorological Society
Abstract: The South American monsoon system (SAMS) refers to the austral summer season features of deep convective activity and large-scale circulation. This study examines intraseasonal variations in the low-level wind circulation ...
Changes in the Activity of the Madden–Julian Oscillation during 1958–2004
Publisher: American Meteorological Society
Abstract: The Madden?Julian oscillation (MJO) is the most prominent mode of tropical intraseasonal variability. This study investigates the following questions. Is there statistical evidence of linear trends in MJO activity since ...
Forecast Skill of Synoptic Conditions Associated with Santa Ana Winds in Southern California
Publisher: American Meteorological Society
Abstract: Santa Ana winds (SAW) are synoptically driven mesoscale winds observed in Southern California usually during late fall and winter. Because of the complex topography of the region, SAW episodes can sometimes be extremely ...
Influence of the Madden–Julian Oscillation on Forecasts of Extreme Precipitation in the Contiguous United States
Publisher: American Meteorological Society
Abstract: Extreme precipitation events are among the most devastating weather phenomena since they are frequently accompanied by loss of life and property. This study uses reforecasts of the NCEP Climate Forecast System (CFS.v1) to ...
Forecast Skill of the South American Monsoon System
Publisher: American Meteorological Society
Abstract: he South American monsoon system (SAMS) is the most important climatic feature in South America and is characterized by pronounced seasonality in precipitation. This study uses the National Centers for Environmental ...
Interannual Variability of Daily Extreme Precipitation Events in the State of São Paulo, Brazil
Publisher: American Meteorological Society
Abstract: The climatology and interannual variability of heavy, or ?extreme,? precipitation events are studied, using station data from the state of S?o Paulo, Brazil. An extreme event is defined at each station when daily rainfall ...
