What fraction of Atlantic hurricanes will actually make landfall on the East Coast of the U.S? 4. How many days in advance did the European model predict Sandy's left turn into the East Coast? 5. What does NOAA stand for? What was the first unusual meteorological condition (or the lack-there-of) responsible for the landfall of Sandy? 6. 7. How many degrees above normal were the ocean temperatures in the North Atlantic? 8. What was the type of storm Sandy merged with? 9. What was the ridiculous nickname the media gave Sandy? 10. What is the name of the previous Hurricane that gave New Yorkers a 'false sense' of security?Explanation / Answer
1.which number was sandy on the list of Atlantic tropical stroam of 2012:
Answer:
TheAtlantichurricane season featured the third most named stroams for the thirdcobsecutive year on record. Though the season offically egan on June 1 and ended on November 30, dates which conventionally delimit the period of each year when most tropical cyclones develope in the Atlantic basin, two stroms Alberto and Benrly. it was developed before the official start, on May 19. and May 26,respectively. This was the first storam such occurrance since 1980 season.The season's final strom toform, Tony, dissipatedon October25,although the previous cyclone, sandy, did not do so until four days later.
The seson produced ninteen tropical cyclones, all of which intensified into tropical stroms ten became hurricanes, but only two strengthed into major hurricanes. Strom impact during the season was widespread and ruinous, with the most significant stroms in terms of loss of life and damage being hurricanes Issac and sandy, A category 1 on the Saffir simpson hurricand wind scale, Issac was a large system that moved ashore the cost of Lousisana on August 12, the strom resulted in 41 deaths overall. Sandy. the second and final major hurricane of the season, was largest Atlantic hurricane ever recorded, with a wind diameter of more than 1,100mi (1800km). The system moved ashore the southern coast of New Jersey as extra tropical cyclone in late damage and 285 fatalities. Sandy is the second- costliest Atlantic hurricane in recorded history, surpassed only byHurricane Katrina 2005 season.
2. what isthe minimum approximate ocean temperature neededintropical strom:
Answer:
Tropical cyclogenesis is the development and strengthing of a tropica lcyclone in the atmosphere.The mechanisms through which tropical cyclogenesis occurs are distinctly different from those throughwhich mid= latitude cyclogenesis owwurs. Tropical cyclogenesis involves the development of warm-core cyslone, due to significant convection in afavorable sufficietly warm sea surface temperatures atleast 26.50C (800F), atmospheric indtability,high humiditity in the lower to middle levels troposphere, enough Corolis force to develop a low pressure cntre, a preexisiting low level focus or disturbance, and low vrtical wind shear. Tropical cyclones tend to during the summer. but have been noted in nearly every month in most basins. climate cycles such ans ENSO and the Madden -Jullian oscillation modulate the timig and frequency of tropical cyclone development, There is a limit on tropical cyclone intensity which is strongly related to the water temperatures along its path. An average of 86 tropical cyclones of tropical strom intenesity form annually worldwide. Of those, 47 reach hurricane/typhoon strength, and 20 becaome intense tropical cyclones.Normally, an ocean temperature of 26.50C spanning through at least a 50 metre depth is considered the minimum to maintain a tropical cyclone. These warm waters are needed to maintain the warm core that fuels tropicalsystems. This value is well above 16.10C (60.90F),the globla average surface temperatureof the oceans.Tropical cyclones are known to form even when normal conditions are not met. For example, cooler air temperature at a higher altitude ( at the 500 hPa level or 5.9 km) can lead to the atmosphere to tropical cyclogenesis at lower water temperatures, certain lapse rate is required to force at the atmosphere to be unstable enough for convection. In a moist atmosphere, this lapse rate is 6.50C/km. while less than 100% relative humidity,the required lapse rate is 9.80C/km..
