Available in PDF, EPUB and Kindle. Book excerpt: This is a preliminary report on use of satellite cloud imagery to forecast tropical cyclone movements. The spatial distribution of cloudiness implicitly indicates information about recent or ongoing processes in the atmosphere. Assuming that as with cloud distribution represents a set of initial conditions, it is reasonable to expect that forecast information can be extracted from these initial conditions. The problem with using satellite imagery as a self-contained forecast tool has been the difficulty in handling the data processing. The Man-computer Interactive Data Access System (McIDAS) is a flexible data management system the advantages of both human decision-making computer. With McIDAS it is relatively simple to assemble composites of images of storms with similar displacement characteristics. These composites reinforce the cloud or cloudless features common to the individual cases and mute randomly distributed clouds. Investigation of typhoon cloudiness in the Pacific indicate that there are different characteristic cloud distributions preceding storms that recurve and those that stay on westerly tracks. In particular there is a confluence of outflow cloudiness from the storm with the clouds of a mid-latitude frontal system in the case of low-latitude westward moving storms in the Philippine and South China Seas. Characteristic cloud patterns associated with other types of storm systems are also suggested by the analysis.

Download or read book Positioning Tropical Cyclones in Satellite Imagery written by WEATHER WING (1ST) HICKAM AFB HI. and published by . This book was released on 1981 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: A three step operational approach to positioning Pacific-based tropical cyclones in satellite imagery is presented. In the pre- analysis stage the image is acquired, selectively processed, and correctly gridded. During the analysis stage the circulation center of the cyclone is fixed based on cloud features in the image. In the third stage, post-analysis, quality control procedures assure optimum accuracy of the determined position fix.

This book was released on 1977 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report reviews the work reported earlier in AFGL-TR-76-0170, Cloud Distributions as Indicators of Tropical Storm Displacement, by the same author, on the application of composite cloud imagery to the forecasting of tropical storm motion. Several additional techniques that were tested briefly for application to typhoon specification and forecasting are discussed and evaluated. Animations of 12-hour infrared images did not suggest anything useful within the limited time available for analysis. The technique, however, should be comprehensively tested with data of better time and spatial resolution. Infrared composites appeared to be less useful than visual composites. The increased detectability of thin cirrus clouds in the infrared masked the significant cloud features. An attempt to duplicate Dvorak's relationships between peak wind speed and the central and banding features of typhoons by compositing storms of similar intensity failed. The fine details Dvorak could distinguish in individual storms were destroyed by the compositing process. Objective analysis of satellite imagery of typhoons is seriously handicapped by the limited archive of digital data. (Author).

This book was released on 1997-03-01 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: A better understanding of the role mesoscale convective systems (MCS) play in the formation stages of tropical cyclones will increase the ability to predict their occurrence and motion. This thesis employs high resolution satellite imagery to observe the Interaction between MCSs and their environment. Specifically, thirteen cases of tropical disturbances that eventually developed Into tropical cyclones are analyzed to determine the role of MCSs in increasing the system organization. Following two conceptual models developed during the Tropical Cyclone Motion (TCM-93) mini-field experiment, each tropical cyclone is classified according to the relative importance of MCS activity to its development. Both conceptual models are verified through analysis and a third model is created to account for tropical cyclone developments that share features of the previous two models. An alternate approach is proposed for determining tropical system organization using only visible and infrared satellite imagery.

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.
