Download or read book The Use of Satellite Microwave Rainfall Measurements to Predict Eastern North Pacific Tropical Cyclone Intensity written by Derek A. West and published by . This book was released on 1998 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: This proposed study examines the potential use of satellite passive microwave rainfall measurements derived from Special Sensor Microwave/Imager (SSM/I) radiometers onboard the Defense Meteorological Satellite Program (DMSP) constellation to improve eastern North Pacific Ocean tropical cyclone intensity change forecasting techniques. Relationships between parameters obtained from an operational SSM/I-based rainfall measuring algorithm and 12-, 24-, 36-, 48-, 60- and 72-hour intensity changes from best track data records are examined in an effort to identify statistically significant predictors of intensity change. Correlations between rainfall parameters and intensity change are analyzed using tropical cyclone data from three years, 1992 to 1994. Stratifications based upon tropical cyclone intensity, rate of intensity change, climatology, translation, landfall and synoptic-scale environmental forcing variables are studied to understand factors that may affect a statistical relationship between rainfall parameters and intensity change. The predictive skill of statistically significant rainfall parameters is assessed by using independent tropical cyclone data from another year, 1995. In addition, case studies on individual tropical cyclones are conducted to gain insight on predictive performance and operational implementation issues.
Download or read book Forecasting 24 and 48 Hour Intensity Changes for Northwestern Pacific Tropical Cyclones Using Satellite Imagery written by Richard W. Hartman and published by . This book was released on 1989 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sixteen years of typhoon data were studied, in an effort to develop a technique for forecasting tropical cyclone intensity changes in the Northwestern Pacific. The data base provided average changes for 24 and 48 hour periods along with the average duration of each phase (intensifying and dissipating). Further study revealed that the upper-level outflow patterns provide a means to adjust these average changes so a more realistic forecast could be generated for the individual storms. Forecasts were further improved by studying how land and other environmental features effect the life cycle of tropical cyclones. Results from the research were compiled and incorporated into a series of flow charts. These charts were created to enable individuals to quickly determine future intensities of cyclones given the storm's history and a current satellite picture. (emk).

Download or read book A Spiral Analysis Technique for Monitoring and Predicting Tropical Cyclone Intensity Using Satellite Data written by Bernard John Cook and published by . This book was released on 1984 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: A spiral analysis technique is developed which quantifies the spiral patterns of cloud bands observed in IR satellite images of tropical cyclones. The technique utilizes the Navy's SPADS (Satellite Data Processing and Display System) minicomputer for processing the digital IR data. The technique consists of best fitting spherical-logarithmic spirals to tropical cyclone spiral cloud bands and performing multiple Fourier analyses of the radiance field along spirals orthogonal to the bands. Linear regression techniques are used to establish a relationship between spiral parameters derived from the Fourier analyses and tropical cyclone intensity. Algorithms for current intensity, and 12 and 24 h forecasts are developed. Tests on an independent data set show significant skill in estimating current intensity and in making 12 h forecasts. The most important predictors selected are presistence and parameters related to the dominant spiral signal and maximum IR count of the analyzed radiance field. Biases in the forecast algorithms suggest that other parameters are necessary to more accurately predict tropical cyclone intensity. The results, however, demonstrate the usefulness of the technique as an aid to tropical cyclone forecasters.
Download or read book Global Perspectives On Tropical Cyclones From Science To Mitigation written by Johnny C L Chan and published by World Scientific. This book was released on 2010-04-30 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a completely rewritten, updated and expanded new edition of the original Global Perspectives on Tropical Cyclones published in 1995. It presents a comprehensive review of the state of science and forecasting of tropical cyclones together with the application of this science to disaster mitigation, hence the tag: From Science to Mitigation.Since the previous volume, enormous progress in understanding tropical cyclones has been achieved. These advances range from the theoretical through to ever more sophisticated computer modeling, all underpinned by a vast and growing range of observations from airborne, space and ocean observation platforms. The growth in observational capability is reflected by the inclusion of three new chapters on this topic. The chapter on the effects of climate change on tropical cyclone activity is also new, and appropriate given the recent intense debate on this issue. The advances in the understanding of tropical cyclones which have led to significant improvements in forecasting track, intensity, rainfall and storm surge, are reviewed in detail over three chapters. For the first time, a chapter on seasonal prediction is included. The book concludes with an important chapter on disaster mitigation, which is timely given the enormous loss of life in recent tropical cyclone disasters.World Scientific Series on Asia-Pacific Weather and Climate is indexed in SCOPUS.

Download or read book Using SSM I Data and Computer Vision to Estimate Tropical Cyclone Intensity written by and published by . This book was released on 1998 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: Satellite imagery and other remote sensing products often provide the only observational data of tropical cyclones. This is especially true in the western Pacific where aircraft reconnaissance missions stopped in 1987. Manual estimate procedures using satellite imagery (Dvorak, 1984) provide valuable assistance in determining tropical cyclone intensity. An objective Dvorak technique (Velden, et al., 1998) is currently being studied to enhance the manual method. In an effort to take advantage of the unique characteristics (Hawkins, et al., 1998) of Special Sensor Microwave/Imager (SSM/I) data, one Naval Research Laboratory effort (outside the scope of this paper) involves the computation of empirical orthogonal functions of SSM/I tropical cyclone data and presenting those values as inputs to a neural network to estimate the tropical cyclone intensity at a given imagery time (May, et al., 1997). The algorithm applied in the research described here also uses SSM/l data, specifically the 85 GHz (H-pol) channel and a derived rain rate product. The 512x512 pixel imagery is cyclone-centered and image characteristics (computer vision features) are computed from the imagery data. A subset of these -features is presented to a pattern recognition algorithm (k-nearest neighbor) and an intensity estimate is provided as output. A description of the imagery characteristics (including available data and computer vision features) and feature selection methodology is provided in section two. Section three is a discussion of the algorithm used to automate the tropical cyclone intensity estimate and the current evaluation results.
