RISA Dynamic Decision Model Applied to Hurricane Landfall
Publisher: American Meteorological Society
Abstract: The decision to prepare for an oncoming hurricane is typically framed as a static cost:loss problem, based on a strike-probability forecast. The value of waiting for updated forecasts is therefore neglected. In this paper, ...
Interpretation of Extended Empirical Orthogonal Function (EEOF) Analysis
Publisher: American Meteorological Society
Abstract: Application of an empirical orthogonal function (EOF) analysis to a data matrix that contains two or more variable fields has been referred to as extended EOF (EEOF) analysis. Coherence between individual features contained ...
Large-Scale Circulation Variability over the Tropical Western North Pacific. Part I: Spatial Patterns and Tropical Cyclone Characteristics
Publisher: American Meteorological Society
Abstract: The basic structure of the variability of the large-scale circulations over the tropical western Pacific is investigated with respect to its influence on tropical cyclone characteristics. A vector empirical orthogonal ...
Structure of a Mesoscale Convective System Embedded in Typhoon Robyn during TCM-93
Publisher: American Meteorological Society
Abstract: A mesoscale convective system (MCS) embedded in the circulation of Typhoon (TY) Robyn was investigated by two aircraft missions during the tropical cyclone motion (TCM-93) mini field experiment. The MCS initially formed ...
Extratropical Transition of Tropical Cyclones over the Western North Pacific. Part I: Evolution of Structural Characteristics during the Transition Process
Publisher: American Meteorological Society
Abstract: The development of extratropical cyclone structural characteristics that resulted from the extratropical transition of Typhoon (TY) David (1997) and TY Opal (1997) over the western North Pacific is examined. David moved ...
Tropical Cyclone Track Characteristics as a Function of Large-Scale Circulation Anomalies
Publisher: American Meteorological Society
Abstract: Factors that contribute to intraseasonal variability in western North Pacific tropical cyclone track types are investigated. It is hypothesized that the 700-mb large-scale circulation can affect tropical cyclone track ...
Downstream Development Associated with the Extratropical Transition of Tropical Cyclones over the Western North Pacific
Publisher: American Meteorological Society
Abstract: The movement of a tropical cyclone into the midlatitudes involves interactions among many complex physical processes over a variety of space and time scales. Furthermore, the extratropical transition (ET) of a tropical ...
A Technique for Analyzing Optimal Relationships among Multiple Sets of Data Fields. Part 1: The Method
Publisher: American Meteorological Society
Abstract: A multiple-set canonical correlation analysis (MCCA), which can be used to study atmospheric motions by analyzing the relationships among more than two sets of data fields, is proposed. By using the product or squared ...
Environmental Conditions Prior to Formation of a Midget Tropical Cyclone during TCM-93
Publisher: American Meteorological Society
Abstract: During a 10-day period in the Tropical Cyclone Motion (TCM-93) field experiment over the tropical western North Pacific, tropical cyclone formation occurred in association with persistent deep convection that was observed ...
Extratropical Transition of Tropical Cyclones over the Western North Pacific. Part II: The Impact of Midlatitude Circulation Characteristics
Publisher: American Meteorological Society
Abstract: Two characteristic midlatitude circulation patterns (labeled northwest and northeast) are found to be associated with extratropical transition (ET) of tropical cyclones over the western North Pacific Ocean. Although in ...
