Intensifying into a Hurricane, Sandy made landfall first near Kingston, Jamaica on October 24th and after reaching Category 2 Hurricane status struck Cuba the next day. After killing 70 people in Haiti, Dominican Republic, Puerto Rico, Cuba and the Bahamas, Hurricane Sandy pointed north and moved towards the East Coast of the United States. Sandy eventually moved ashore near Atlantic City, New Jersey and New York City on October 29th as a post-tropical cyclone with hurricane force winds. All said and done Superstorm Sandy (as it was termed after it joined a cold-core low pressure system moving eastward at the same time) affected an astounding total of 24 U.S. states. Most of the damage occurred in the Mid-Atlantic States. Sandy even caused the formation of an intense snowstorm in the high altitude regions of West Virginia. #> #>-The Supreme Court, New York City Stock Exchange, Amtrak, and nearly all airports and railways near the East Coast were closed for two days #>-Nearly 20,000 flights were canceled in all. #>-The New York City Subway was still trying to repair the damage six weeks later. #>- Total damage in the US is estimated at over $63 billion. #> #>1) Real-time Linear IR #>-IR Satellite images from GOES show clouds by measuring the infrared radiation emitted, which is directly proportional to the temperature #>-Bright white clouds are higher and colder whereas grey clouds are lower and warmer #>-Hurricane Sandy Developed in place in the Caribbean Sea, made landfall in Jamaica, Haiti, Dominican Republic, Puerto Rico, Cuba and the Bahamas as a Category 1 & 2 hurricane, lost its shape in southern Atlantic ocean heading northward but held its strength, turned west and slowly came ashore near Atlantic City, NJ, the highest storm surge reached 13 feet in Lower Manhattan #> #>2) SST Anomaly #>-Warm temperatures in the ocean drive hurricane intensity – ocean temperatures typically are above 80°F (26.5°C) for hurricane formation #>-3° C (5.4°F) higher than average SST in the Gulf Stream of which 0.6° C (1.08°F) is thought to be as a result of global warming #>-Red is higher than normal, white is normal, blue is cooler than normal #>-You can see a trail of cooler water following a hurricane once the heat has been transferred as energy for the storm #> #>3) GLAPS 500mb Heights and Windspeed #>-Contour lines show lines of equal height at the 500mb pressure level which is roughly the halfway point in the atmosphere #>-The 500 mb pressure level is around 18,000 feet above the surface and varies in height based on pressure.
