Intense means that near surface sustained2 wind speeds exceed 17 ms¡1 (60 km h¡1, 32 kn).Severe tropical cyclones with near characteristics of tropical cyclone rainfall. The primary objectives of this research are to identify these factors and determine how they impact each of these tropical cyclone characteristics. INTRODUCTION Tropical cyclone (TC) intensification involves the interaction of processes on a wide spectrum of tropical or subtropical waters and has a closed low-level circulation. A study of tropical cyclone influence on the generation of internal tides Fraser J. M. Davidson1 and Peter E. Holloway2 School of Geography and Oceanography, University of … Major storm systems over Europe frequently have a tropical origin. Tropical Storm— A tropical cyclone … • Tropical Storm: develops if a tropical depression intensifies Wind speeds > 60 km/h At this point, the system is named ~80-100 tropical storms per year in world oceans ~10 tropical storms per year in the Atlantic Ocean • Hurricane: develops from tropical storm Wind speeds > 120 km/h ~40 hurricanes per year in the world oceans Tropical cyclone frequency, motion, and structure characteristics depend on a variety of environmental and internal factors. Chapter 1 OBSERVATIONS OF TROPICAL CYCLONES Tropical cyclones are intense, cyclonically1-rotating, low-pressure weather systems that form over the tropical oceans. CHARACTERISTICS OF TROPICAL CYCLONE RAPID INTENSIFICATION IN ENVIRONMENTS OF UPPER-TROPOSPHERIC TROUGHS Michael S. Fischer*, Brian H. Tang, and Kristen L. Corbosiero University at Albany, SUNY 1. More specifically, this study employs an exploratory data analysis (EDA) approach (Tukey, 1977) to gain further insight into the statistical properties of daily tropical cyclone rainfall over affected areas of the United States. This paper analyses the characteristics and dynamics of such cyclones in the observational record, using MERRA reanalysis data for the period 1979-2013. the internal tropical cyclone structure influence tropical cyclone track and intensity characteristics and define how these influences differ between developing, mature, and decaying tropical cyclones. Tropical cyclones rotate counterclockwise in the Northern Hemisphere. They are classified as follows: Tropical Depression—A tropical cyclone with maximum sustained winds of 38 mph (33 knots) or less. During the initial stages of tropical cyclone development, structure and track characteristics can exhibit
