RISSeasonal Variability in Precipitation in Central and Southern Chile: Modulation by the South Pacific High
Publisher: American Meteorological Society
Abstract: AbstractMonthly precipitation in Chile (30°?55°S) was found to vary by intensity, latitude, and longitude of the South Pacific high (SPH). In austral winter, precipitation was higher when the SPH was weaker and when it was ...
Using the Amazing atmosphere to Foster Student Learning and Interest in Meteorology
Publisher: American Meteorological Society
Abstract: students in active learning, the Oceanography Department at the United States Naval Academy developed a new, not-for-course-credit training activity for its students, the Severe Weather InField Training (SWIFT). In SWIFT, ...
Links between Tropical Cyclone Activity and Madden–Julian Oscillation Phase in the North Atlantic and Northeast Pacific Basins
Publisher: American Meteorological Society
Abstract: The leading intraseasonal mode of atmospheric and oceanic variability, the Madden?Julian oscillation (MJO), influences tropical and extratropical sea level pressure, temperature, divergent and rotational wind components, ...
Intraseasonal Variability of Hail in the Contiguous United States: Relationship to the Madden–Julian Oscillation
Publisher: American Meteorological Society
Abstract: limatologies have been developed to highlight variability of the frequency and intensity of hail in the United States. However, the intraseasonal variability of hail, including why one week might be active while the following ...
Madden–Julian Oscillation (MJO) Modulation of Atmospheric Circulation and Chilean Winter Precipitation
Publisher: American Meteorological Society
Abstract: he leading intraseasonal mode of tropical atmospheric variability, the Madden?Julian oscillation (MJO), has been shown to modulate precipitation and circulation on a global and regional scale. Winter precipitation in Chile ...
Effect of the Andes Cordillera on Precipitation from a Midlatitude Cold Front
Publisher: American Meteorological Society
Abstract: The effects of the Andes Cordillera, the major mountain range in South America, on precipitation patterns of baroclinic systems approaching from the southeast Pacific remain largely unstudied. This study focuses on a case ...
Multiday Circulation and Precipitation Climatology during Winter Rain Events of Differing Intensities in Central Chile
Publisher: American Meteorological Society
Abstract: he majority of precipitation in central Chile falls during austral winter with the passage of surface and upper-level low pressure systems and their associated surface fronts. Earlier studies have found the presence of a ...
Relationships between Tropical Cyclone Intensity and Eyewall Structure as Determined by Radial Profiles of Inner-Core Infrared Brightness Temperature
Publisher: American Meteorological Society
Abstract: adial profiles of infrared brightness temperature for 2405 different satellite observations from 14 western North Pacific tropical cyclones (TCs) from the 2012 season were analyzed and compared to intensity and changes in ...
An Example of the Value of Strong Climatological Signals in Tropical Cyclone Track Forecasting: Hurricane Ivan (2004)
Publisher: American Meteorological Society
Abstract: Since 1970, tropical cyclone (TC) track forecasts have improved steadily in the Atlantic basin. This improvement has been linked primarily to advances in numerical weather prediction (NWP) models. Concurrently, with few ...
Some Climatological Aspects of the Madden–Julian Oscillation (MJO)
Publisher: American Meteorological Society
Abstract: ne of the most commonly used metrics for both locating the Madden?Julian oscillation (MJO) geographically and defining the intensity of MJO convective activity is the real-time multivariate MJO (RMM) index. However, a ...
