The intensity of tropical cyclones hitting East Asia has significantly increased over the past 30 years, according to a new study published today. The coastlines of China, Korea and Japan in particular have experienced increasingly stronger cyclones, which the researchers have attributed to increasing sea surface temperatures and a change in atmospheric circulation patterns over the coastal seas. According to the study, the changes in sea surface temperature and wind flows meant that...

Tropical Storms Gain Strength Over Land Due To 'Brown Ocean' Phenomenon

April Flowers for redOrbit.com - Your Universe Online Meteorologists were stumped by Tropical Storm Erin in 2007. Unlike most tropical cyclones, which dissipate after making landfall and being weakened by everything from friction and wind shear to loss of the ocean as a source of heat energy, Erin intensified as it tracked through Texas. Erin's eye formed over Oklahoma, and grew stronger than it had been over the ocean as it spun over the southern plains. According to NASA-funded...

Due To Earlier Monsoon Onset Tropical Cyclones In The Arabian Sea Have Intensified
2012-09-24 08:20:47

The tropical cyclones in the Arabian Sea during the pre-monsoon season (May — June) have intensified since 1997 compared to 1979 - 1997. This has been attributed to decreased vertical wind shear due to the dimming effects of increased anthropogenic black carbon and sulfate emissions in the region. The decrease in vertical wind shear, however, is not the result of these emissions, but due to a 15-day on average earlier occurrence of tropical cyclones, according to a study spearheaded by...

Tropical Cyclones To Cause Greater Damage In The Future

Tropical cyclones will cause $109 billion in damages by 2100, according to Yale and MIT researchers in a paper published in Nature Climate Change. That figure represents an increased vulnerability from population and especially economic growth, as well as the effects of climate change. Greater vulnerability to cyclones is expected to increase global tropical damage to $56 billion by 2100–double the current damage–from the current rate of $26 billion per year if the present...

More frequent tropical cyclones in Earth's ancient past contributed to persistent El Niño-like conditions, according to a team of climate scientists led by Yale University. Their findings, which appear in the Feb. 25 issue of the journal Nature, could have implications for the planet's future as global temperatures continue to rise due to climate change. The team used both cyclone and climate models to study the frequency and distribution of tropical cyclones (also known...

A recent NASA study suggests that tiny dust particles may have foiled forecasts that the 2006 hurricane season would be another active one. In June and July 2006, there were several significant dust storms over the Sahara Desert in Africa. As this dust traveled westward into the Atlantic, satellite data show that the particles blocked sunlight from reaching the ocean surface, causing ocean waters to cool. These cooler waters may have impeded some storminess since hurricanes rely on warm...


Word of the Day
toccata
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
