RISQuasi-Biweekly Oscillation of the Convection around Sumatra and Low-Level Tropical Circulation in Boreal Spring
Publisher: American Meteorological Society
Abstract: The quasi-biweekly oscillation (QBWO) of the tropical convection around Sumatra and its relation to the low-level circulation over the tropical Indian Ocean in boreal spring is investigated. From March to May, the convection ...
The SST Gradient between the Southwestern Pacific and the Western Pacific Warm Pool: A New Factor Controlling the Northwestern Pacific Tropical Cyclone Genesis Frequency
Publisher: American Meteorological Society
Abstract: he sea surface temperature gradient (SSTG) between the southwestern Pacific Ocean (40°?20°S, 160°E?170°W) and the western Pacific warm pool (0°?16°N, 125°?165°E) in boreal spring has been identified as a new factor that ...
Relationship between the Asian Westerly Jet Stream and Summer Rainfall over Central Asia and North China: Roles of the Indian Monsoon and the South Asian High
Publisher: American Meteorological Society
Abstract: AbstractDiagnostic analyses are performed to investigate the relationship between the upper-level Asian westerly jet stream (AWJS) and the associated rainfall pattern over the AWJS region in boreal summer on interannual ...
Structure and Origin of the Quasi-Biweekly Oscillation over the Tropical Indian Ocean in Boreal Spring
Publisher: American Meteorological Society
Abstract: The structure and evolution features of the quasi-biweekly (10?20 day) oscillation (QBWO) in boreal spring over the tropical Indian Ocean (IO) are investigated using 27-yr daily outgoing longwave radiation (OLR) and the ...
Impacts of Model Resolutions and Initial Conditions on Predictions of the Asian Summer Monsoon by the NCEP Climate Forecast System
Publisher: American Meteorological Society
Abstract: series of 60-day hindcasts by the Climate Forecast System (CFS) of the National Centers for Environmental Prediction is analyzed to understand the impacts of atmospheric model resolutions and initial conditions on predictions ...
An Analysis of the Large-Scale Climate Anomalies Associated with the Snowstorms Affecting China in January 2008
Publisher: American Meteorological Society
Abstract: Extraordinarily frequent and long-lasting snowstorms affected China in January 2008, causing above-normal precipitation, below-normal temperature, and severe icing conditions over central?southern China. These snowstorms ...
Characteristics of the Dominant Modes of Atmospheric Quasi-Biweekly Oscillation over Tropical–Subtropical Americas
Publisher: American Meteorological Society
Abstract: uring the boreal summer (June?August), vigorous convection appears over the eastern Pacific, southern Mexico, and northern South America, and oscillates on a distinct time scale of 10?20 days. Extended empirical orthogonal ...
Variations of U.S. Regional Precipitation and Simulations by the NCEP CFS: Focus on the Southwest
Publisher: American Meteorological Society
Abstract: Variations of U.S. regional precipitation in both observations and free-run experiments with the NCEP Climate Forecast System (CFS) are investigated. The seasonality of precipitation over the continental United States and ...
Interannual Variation of the South Asian High and Its Relation with Indian and East Asian Summer Monsoon Rainfall
Publisher: American Meteorological Society
Abstract: diagnostic analysis reveals that on the interannual time scale the southeast?northwest movement is a dominant feature of the South Asian high (SAH), and it is closely related to the Indian and East Asian summer monsoon ...
Time–Frequency Characteristics of Regional Climate over Northeast China and Their Relationships with Atmospheric Circulation Patterns
Publisher: American Meteorological Society
Abstract: The time?frequency characteristics of the variations of temperature and precipitation over the city of Changchun in northeast China and their associations with large-scale atmospheric and oceanic conditions are analyzed. ...
