Meteorological Conditions that Created Hurricane Sandy
In late October of 2012 many weather factors converged to create Hurricane Sandy, a huge storm with winds gusting up to 90 miles per hour. This hurricane was unprecedented in modern times, arriving late in the hurricane season, making landfall abnormally far to the north on the United States east coast with an exceptionally low pressure and a record breaking storm surge. Sandy also had among the most kinetic energy of all tropical cyclones on record at 222 Joules, more energy than category 5 hurricanes, despite just being category 1 because of the large area over which she spread.
Sandy, like all hurricanes, originated in the tropics. Normally a storm like Sandy would diminish in intensity as it moved into colder, less energetic waters of the north, however a trough of low pressure dipping down from the Arctic worked to intensify the storm, actually strengthening it as it moved northward. Higher tides, because of a full moon, also are credited to an increase in flooding. Another factor that exacerbated the situation was a block of high pressure in the northeastern Atlantic Ocean that pushed the hurricane onshore.
There is speculation that climate change may have also have contributed to the storms intensity. Global warming may have made Sandy wetter and stronger. Hurricanes and tropical storms are fueled by warm water evaporating into the air. Records indicate that ocean surface temperatures are up 0.9 degrees
