Abstract: The objective of this research is to define the meteorological conditions prior to the explosive development of the QE II storm. By using conventional data and detailed McIDAS satellite imagery we document the genesis of ...

Abstract: The existence of convection and the hurricane-like structure in the explosively-developing cyclone studied in Part I motivates us to assess the importance heating had on this cyclogenesis. To accomplish this, a method to ...

Abstract: On Friday, 10 December 1982, a modest, yet unforecasted snowfall occurred in a band extending from the Ohio valley states eastward to western New York State. Aside from this case study representing a crucial forecasting ...

Abstract: The hurricane-force winds and heavy seas which battered the liner Queen Elizabeth II on 10 and 11 September 1978 were associated with an extreme example of a meteorological ?bomb? as defined by Sanders and Gyakum. Despite ...

Abstract: Six years of daily temperature and precipitation forecasting are studied for Urbana, Illinois. Minimum temperature forecast skills, measured against a climatological control, are 57%, 48%, 34% and 20% for the respective ...

Abstract: By defining a ?bomb? as an extratropical surface cyclone whose central pressure fall averages at least 1 mb h?1 for 24 h, we have studied this explosive cyclogenesis in the Northern Hemisphere during the period September ...

Abstract: modified blocking index is defined based on vertically integrated potential vorticity. The application of this index identifies blocking activity over the Northern Hemisphere during all seasons. The index is developed by ...

Abstract: The continental cyclone of 28?29 March 1984 was noteworthy for its explosive intensification within six hours. Surface and upper-air data are analyzed for this storm throughout its 18-h life cycle of growth and decay over ...

Abstract: The various modes of atmospheric mass redistribution characterize the principal variations of the general circulation of the atmosphere. Interhemispheric exchanges of atmospheric mass occur with considerable regularity on ...
