What Are Nor’easters and Coastal Storms?
A storm on the coast that is located in the northeast is referred to as a nor’easter. Its winds originate from the northeast and spread across the coastal areas. Coastal erosion and nor Easter are the similar terms having same meaning. The impact of these storms could be comparable to hurricanes. Nor’easters usually occur between September and October. If winter is at its peak, it is possible to see them during winter storms.
The risks that Nor’easters create, as well as the coastal weather, are primarily caused by storm surges that have strong winds, extreme snow, heavy rain on shores as well as beaches being destroyed by the rip waters. Nor’easters typically last more than a few days and can impact many waves.
Types of Nor’easters
Nor’easters fall into two types that researcher J. E. Miller invented in 1946. The most common nor’easter type, the most well-known, is called Miller Type A nor’easter. The classic nor’easters originate in the Gulf of Mexico and develop into full-blown storms, which then traverse all of the East Coast.
Miller Type B and Easter’s are storms with low pressure that originate from the regions within The United States Midwest. The less frequent storms shrink after crossing the Appalachian Mountains and reforming into nor’easters along the East Coast.
Impacts of Nor’Easters
Nor’easters are most often seen within the region’s latitudes between Georgia and New Jersey. Georgia and New Jersey, almost 100 miles east toward East Coast, they are most likely to shift toward the northeast and typically get their most incredible intensity close to England and the some Provinces of Canada.
They generally brought up massive snow or rain, powerful winds, rough water, and sometimes coastal flooding to affected areas. The area in which residents reside in New York, Philadelphia, Boston and Washington D.C. The “I-95 Corridor,” is mainly affected by nor easters.
How to overcome coastal erosion and nor Easters?
Forecasters of weather for NWS Local offices that provide forecasts throughout the country and are located in the National Centers for Environmental Prediction seek out situations favorable to nor easters, particularly in the spring and winter.
Suppose they find conditions that favor in future. In that case, forecasters will issue warnings about winter storms or blizzards as well as high winds as coast flooding warnings to inform people living there of the worst impacts of coastal erosion and Nor’easters are most likely. If there is a risk that there is imminent risk, the watch is upgraded to warn.
Beach erosion along the shoreline is one of the most severe effects of coastal erosion. This is because the length of the coastline is an indication of the vulnerability to erosion of the beach, particularly coastal properties.
Storm waves and duration and tides are the three main variables that determine the likelihood of erosion during storms. Many researchers have suggested erosion indexes for large storms based on the strength of storms measured by the speed of wind or length of waves.
However, the impact on the nature of storm tides was never fully examined in prior studies. The possibility of erosion occurring during severe nor’easters depends on the force of the tide more than the length and strength of waves. So, we’ve created an indicator of the risk of erosion during storms that are based upon storm tide, which is the daily measurement of levels of water. The threat of coastal erosion measured (SEPI) can be described in terms of daily surges and the level of storm tides. Also, it has a strong correlation to the actual erosion.The proposal of U.S to Avoid Coastal Erosion and Nor’Easters is given below:
The U.S. provides the ideal fertile soul for nor’easters. In cold, jet stream of the Polar Jet moves cold Arctic air southwards over the plains situated in U.S as well as in the Canada, then east towards the Atlantic Ocean, where hot air originates from the Atlantic and the Gulf of Mexico moves towards north.
Warm waters of the Gulf Stream manage to keep the coastal waters cool during the cold weather, this assists the warming winter cold air above the water. The temperature difference of the hot air above the water and cold Arctic air over the land powers the engines which drive the nor’easters. So, by using few precautionary measurements we can avoid thorough these natural disasters.
