This book was released on 2018-09-15 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: This project tested a novel method that uses satellite imagery to correct phase errors in the initial state for numerical weather prediction, applied to hurricane forecasts. The system was tested on hurricanes Guillermo (1997), Felicia (1997) and Iniki (1992). We compared the performance of the system with and without phase correction to a procedure that uses bogus data in the initial state, similar to current operational procedures. The phase correction keeps the hurricane on track in the analysis and is far superior to a system without phase correction. Compared to operational procedure, phase correction generates somewhat worse 3-day forecast of the hurricane track, but better forecast of intensity. It is believed that the phase correction module would work best in the context of 4-dimensional variational data assimilation. Very little modification to 4DVar would be required.Louis, Jean-FrancoisGoddard Space Flight CenterNUMERICAL WEATHER FORECASTING; HURRICANES; PHASE ERROR; SATELLITE IMAGERY; ATMOSPHERIC MODELS; SATELLITE SOUNDING; APPLICATIONS PROGRAMS (COMPUTERS); CALIBRATING; RADIOSONDES

This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Damage assessment in the wake of a hurricane natural disaster event becomes crucial for first responders and officials for planning and decision-making. Analysis of such damage in cities from satellite images has been historically conducted due to large area coverage, speed of analysis and ability to integrate with other information sources. However, traditional methods of quantifying the extent of damage can be tedious and work-intensive. This thesis aims to explore the use of deep learning methodology for hurricane damage assessment from satellite images. Here, the damage assessment is proposed to be achieved using a set of convolutional neural networks to segment buildings from pre-hurricane imagery and building damage into four categories from post-event images. Data includes WorldView-2 and GeoEye-1 very-high-resolution satellite images for a case study of Hurricane Michael. Emphasis is put onto classification of change into multiple degrees of damage and comparison with a traditional shallow learning classification method. Results show improved accuracy and promise of further use of deep learning in disaster management and recovery. After quantifying a building footprint, this method can be applied onto a new area in the wake of a hurricane to automatically assess damage or monitor recovery efforts. Finally, the developed method can be integrated into emergency response frameworks and utilized for prioritization of relief efforts.

Book excerpt: Weather, in all its variety and majesty, is both a source of Earth's awe-inspiring beauty and a powerful, threatening force. With the brilliant technological innovations of recent times, including lasers, satellites, and supercomputers, scientists have revolutionized the science of accurate weather prediction. As this intriguing work shows, the gap between the "art" and science of forecasting is rapidly narrowing, and the day when we will have accurate weekly and monthly, even yearly, forecasts is quickly approaching. Jack Fishman and Robert Kalish, acclaimed authors of Global Alert: The Ozone Pollution Crisis, clearly and eloquently explain the makings of weather from everyday winds and precipitation to the worst weather disasters. They show how the power of weather still holds us at its mercy and affects us all. Perilous downdrafts, undetectable by airplane pilots, can hurl landing planes into the runway to their doom. Freezing blasts of snow and ice cause traumatic accidents on our streets. Deadly tornadoes descend from thunderclouds, uprooting trees, devastating farmers' fields, and ripping buildings from their very foundations. And hurricanes, the most awesome storms on Earth, smash into the coast with vicious strength - flooding entire cities, lifting houses out to sea, and flattening acres of forest and farmland. Within the decade, scientists will have made a quantum leap in the ability to make accurate, longrange forecasts. Fishman and Kalish show us the stunning capabilities of a new brand of technology that is bringing about a revolution in weather forecasting. Radar, penetrating deep into the most menacing stormclouds, allows us to "see" the movement of raging winds so we can warn endangered communities before catastrophe strikes. Imminent laser and satellite technology will soon circle our Earth and send clear images of developing storms that will help meteorologists make predictions with an accuracy undreamed of today. In addition to recent breakthroughs, this fascinating work also describes pioneering scientists throughout history who used great technological innovations, from the advent of the computer to rocketry, to further our knowledge of weather and climate. Meteorology has rapidly evolved into a cutting-edge science that has irrevocably increased our understanding of the Earth. This remarkable work shows us the force of weather in all its glory and danger. And it paves the way for the revolution in weather science that will lead us into the future

Download or read book A Numerical Study of the Effect of GOES Sounder Cloud Cleared Brightness Temperatures on the Prediction of Hurricane Felix written by and published by . This book was released on 1999 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: The influence of satellite brightness temperature data on the retrospective numerical prediction of Hurricane Felix is investigated. Satellite data are included as an augmentation to bogus data assimilation (BDA) procedure using a mesoscale adjoint modeling system. Assimilation of satellite brightness temperature data was found to have positive impact on both the intensification and track forecast of the hurricane. The improvements made by the simulations using satellite brightness temperatures were realized by intensifying low-level warm ridge located west of the hurricane, reducing the amount of water vapor below 500 hPa over most areas where satellite data are available, and modifying the structures of the initial vortex in the model initial condition. Although being located over a region devoid of satellite data, the initial vortex obtained using both the satellite and bogus surface low data is more realistic than the one using only the bogus data. Despite the fact that the forecast (3.5 days) using only the bogus surface low at the initial time was quite good, track and intensity forecasts beyond 2 days of model integration were shown to be further improved by including satellite data in the initialization procedure. Differences in the prediction of Hurricane Felix with and without satellite data were also found in the prediction of upper-level jet, the cold temperature trough ahead of the hurricane, the size of the hurricane eye, and the location of maximum rainfall during the 3.5 day forecast period. While the focus of this study is to assess the impact of the direct use of satellite brightness temperature data on hurricane prediction, we also noted that the BDA experiment assimilating only the bogus data shows a positive impact of the BDA generated hurricane on the environmental flow, as verified by satellite observations.
Download or read book Predictions in Time Series Using Regression Models written by Cory Terrell and published by Scientific e-Resources. This book was released on 2019-09-02 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Regression methods have been a necessary piece of time arrangement investigation for over a century. As of late, new advancements have made real walks in such territories as non-constant information where a direct model isn't fitting. This book acquaints the peruser with fresher improvements and more assorted regression models and methods for time arrangement examination. Open to any individual who knows about the fundamental present day ideas of factual deduction, Regression Models for Time Series Analysis gives a truly necessary examination of late measurable advancements. Essential among them is the imperative class of models known as summed up straight models (GLM) which gives, under a few conditions, a bound together regression hypothesis reasonable for constant, all out, and check information. The creators stretch out GLM methodology deliberately to time arrangement where the essential and covariate information are both arbitrary and stochastically reliant. They acquaint readers with different regression models created amid the most recent thirty years or somewhere in the vicinity and condense traditional and later outcomes concerning state space models.

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.
