We describe an automatic storm-tracking system to help Doppler radar system to detect severe storms such as thunderwith the forecasting of severe storms. In this article, we present the storms and tornadoes. The Doppler radar generates intensity and concepts of fuzzy point, fuzzy vector, fuzzy length of a fuzzy vector, radial velocity images, examples of which are shown in Figures and fuzzy ang...
Trace metal contributions in urban storm water are of concern to environmental managers because of their potential impacts on ambient receiving waters. The mechanisms and processes that influence temporal and spatial patterns of trace metal loading in urban storm water, however, are not well understood. The goals of the present study were to quantify trace metal event mean concentration (EMC), ...
There are many models for hindcasting ice loads from meteorological data measured during freezing rain storms. Each model is based on the physics of the ice accretion process and on empirical observations. However, these models predict significantly different ice loads for the same freezing rain storm, making it difficult to use model results to determine design ice loads. In this paper, we des...
FPGA has found an increasingly wide utilization in automatic train control (ATC) equipment used in highspeed rail systems, which is potentially sensitive to radiation. How the space radiation caused by Geomagnetic storm affects FPGA devices was analyzed. This paper investigated the FPGA fault-tolerance techniques used nowadays and presented a new mitigation technique against upsets, duplication...

How the space radiation caused by Geomagnetic storm affects FPGA devices was analyzed. This paper investigated the FPGA fault-tolerant techniques used nowadays and presented a new mitigation technique based on duplication with co...
The impacts of environmental moisture on the intensification of a tropical cyclone (TC) are investigated in the Weather Research and Forecasting (WRF) model, with a focus on the azimuthal asymmetry of the moisture impacts relative to the storm path. A series of sensitivity experiments with varying moisture perturbations in the environment are conducted and the Marsupial Paradigm framework is em...
Exceptionally severe winter storms that overwhelm local government result in major disaster declarations. Each National Weather Service forecast office in the United States reports winter events for a specific group of counties, known as the county warning area. Such events are reported as blizzard, ice storm, winter storm, heavy snow, or winter weather. They are archived by the National Climat...
Zonal-mean storm-track shifts in response to perturbations in climate occur even in idealized simulations of dry atmospheres with axisymmetric forcing. Nonetheless, a generally accepted theory of the mechanisms controlling the storm-track shifts is still lacking. Here, mean available potential energy (MAPE), a general measure of baroclinicity that is proportional to the square of the Eady growt...
Evaporation from the sea surface, primarily within a hurricane’s core, provides the heat energy required to intensify and maintain the storm (e.g. Cione and Uhlhorn 2003, Emanuel 2003, and references therein). If the sea surface temperature (SST) decreases within the storm core, so does the heat energy available to the storm. Generally, in the deep ocean, SST cooling within the storm core occur...
Extreme storms and storm surges may induce major changes along sandy barrier coastlines, potentially causing substantial environmental and economic damage.We show that themost destructive storm (the 1634 AD storm) documented for the northern Wadden Sea within the last thousand years both caused permanent barrier breaching and initiated accumulation of up to several metres of marine sand. An agg...
