Environmental Science - Essay ExampleAnd even the general perception about them is that they are little destructive than other storms. For this very reason so little is known about noreasters. Noreasters are said to have caused heavy snow falls in New England and the Middle Atlantic states. In recent years, the US coastal areas have also been hit by a series of noreasters. All this has guide to more attention towards these storms. Researchers have found that apart from their origins in atmospheric disturbances and their cyclonic winds, hurricanes and noreasters bear little resemblance to each other. Hurricanes are warm-core systems and thus limited in height by the colder upper air, while noreasters are cold-core systems that do not lose intensity with height. Unlike hurricanes, noreasters do not necessarily diversity over the open ocean. Noreasters are supposed to require the support of the jet stream to form, so their prevalence is closely related to seasonal changes in the lo cate and the strength of the jet. Correlation of data for the past 50 yrs suggest that the annual frequency of the strongest noreaster is positively correlated with southerly jet-stream position over the eastern US. Winds speed, its duration and the distance are the three factors affecting the growth of waves. With an increase in any of these factors, the height of the storm surge increases. October to April is the uncomplicated noreaster season with February being the most active month. Some of the features of noreasters which can be summarized based on recent studies areBecause of their diffuse structure, they are ticklish to characterize, categorize and predict. Having not able to establish a direct relationship between a noreasters wind speed and its destructive ply has made the task of classification and comparison of these storms more difficult.Researchers assert that one possible cause for the
