Latest Arabian Sea Stories
For the last two days, strong wind shear in the Arabian Sea has pushed most of the clouds and showers associated with Tropical Storm 5A away from its center. Today, Nov. 30, NASA satellite imagery shows wind shear continues to push those clouds to the north and west of 5A's center and is taking a big toll on the entire cyclone. At 03:00 UTC on Nov. 30 (or 10 p.m. EST, Nov. 29), the Joint Typhoon Warning Center issued their final advisory on Tropical Storm 5A (5A). At that time, it was...
A recent increase in the intensity of Arabian Sea cyclones may be the result of increasing air pollution over the Indian sub-continent, according to a new multi-institutional study. Traditionally, prevailing wind shear patterns prohibit cyclones in the Arabian Sea from becoming major storms. However, the study suggests that weakening winds have enabled the formation of stronger cyclones in recent years -- including storms in 2007 and 2010 that were the first recorded storms to enter the...
NASA's TRMM Satellite captured moderate rainfall and some high, towering clouds in the Arabian Sea's newborn Tropical Storm Keila. The TRMM satellite passed directly above a recently formed tropical cyclone in the Arabian Sea on November 2, 2011 at 0350 UTC (11:50 p.m. EDT, Nov. 1). An analysis of rainfall was done using TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments. TRMM data showed that rainfall rates with tropical storm Keila ranged from light to moderate along...
Infrared and visible imagery from NASA's Aqua satellite today hinted that the low pressure area formerly known as Cyclone Jal may have new life soon. Jal has emerged into the warm waters of the Arabian Sea after crossing India this past weekend.The Atmospheric Infrared Sounder (AIRS) instrument that flies onboard Aqua captured infrared and visible images of Jal's remnants on Nov. 9 at 1:30 p.m. local time/India.Today's AIRS imagery hints that circulation is still occurring in Jal's remnants....
The Tropical Rainfall Measuring Mission satellite, known as TRMM is a "flying rain gauge" in space, and can provide rainfall estimates from its position in orbit around the Earth. Data accumulated from TRMM enabled visualizers to create a map of rainfall generated by Cyclone Phet as it marched through the Arabian Sea from May 31 to June 6. The heaviest rainfall occurred over open waters, but Phet dropped very heavy rainfall over parts of Oman and Pakistan.TRMM satellite rainfall...
NASA's Tropical Rainfall Measuring Mission and Aqua satellites are keeping a close eye on Cyclone Phet, a monster cyclone in the Arabian Sea, now affecting coastal Oman. Cyclone Phet's winds and heavy rains reached Oman's east coast earlier today, June 3.Authorities in Oman have raised the threat level to orange, and evacuations have already taken place.Yesterday, when Phet was powering up from a Category three to a Category four cyclone on the Saffir-Simpson scale, the Tropical Rainfall...
After more than a decade of inquiry, a Princeton-led team of scientists has turned the tables on a long-standing controversy to re-establish an old truth about nitrogen mixing in the oceans.For decades, scientists thought they had a handle on the workings of an intricate natural mechanism known as the nitrogen cycle, essential to maintaining life on Earth. This process, one of nature's most elegant sleights-of-hand, shuttles nitrogen from the soils to the oceans to the atmosphere and back.A...
Somali pirates free Malaysian chemical tanker NAIROBI, Sept. 30 (Xinhua) -- Somali pirates have released Malaysian-flagged chemical tanker M/T Bunga Melati which was hijacked off the Gulf of Aden on August 29, a regional maritime official disclosed on Tuesday. Andrew Mwangura of the East African Seafarers' Assistance Program said the chemical tanker owned by Malaysian national carrier MISC was freed after its owners paid a ransom of two million U.S. dollars. "The Somali pirates released...
By Ayash, Tarek Gong, Sunling; Jia, Charles Q ABSTRACT Sea salt aerosols play a dual role in affecting the atmospheric radiative balance. Directly, sea salt particles scatter the incoming solar radiation and absorb the outgoing terrestrial radiation. By acting as cloud condensation nuclei, sea salt aerosols indirectly modulate the atmospheric radiative budget through their effective contribution to cloud formation. Using the Canadian Aerosol Module (CAM)-Canadian Centre for Climate Modelling...
NASA -- Who would have thought that melting snow cover in the Himalayan Mountains could alter the ocean food chain over a thousand miles away? Well, that's just what's happening, according to a NASA-funded study appearing in this week's Science magazine. The study finds a decline in winter and spring snow cover over Southwest Asia and the Himalayan mountain range is creating the right conditions for more widespread blooms of ocean plants in the Arabian Sea. The decrease in snow cover has led...
