Tropical Storm Oli Kicking Up Waves in South Pacific

NASA’s Atmospheric Infrared Sounder (AIRS) instrument captured an infrared image of Oli’s cloud temperatures on February 2 at 0041 UTC. High thunderstorm cloud tops surrounded Oli’s center as cold as minus 63F. There is a separate band of clouds associated with Oli to the north.

At 1500 UTC (10 a.m. ET) on February 2, Oli had maximum sustained winds near 52 mph (45 knots) with higher gusts. It was located about 480 nautical miles west of Bora Bora, near 14.8 South and 159.5 West. Oli has tracked eastward at 11 mph (10 knots).

Lupit and 23W in Western Pacific

Filed under: Cyclone Info, Future Hurricane Names, Hurricane Awarness — admin @ 4:00 am
 

It seems like a common occurrence this season that there are two tropical cyclones spinning in the Western Pacific Ocean and this week, Lupit and newly formed 23W are proof. NASA’s Aqua satellite flew over the Western Pacific early today and captured both storms in one satellite image.

Tropical Storm Lupit is becoming extra-tropical and is expected to track parallel to Japan while remaining at sea, east of the island. Meanwhile, Tropical Storm 23W is approaching Saipan and Andersen Air Force Base and is moving west. The U.S. Navy’s Joint Typhoon Warning Center (JTWC) forecasts tropical cyclones in the Western Pacific Ocean. The JWTC issued their final warning for Extra-tropical Storm Lupit today, October 26 at 0300 UTC (12 a.m. local time Tokyo).

At that time, Lupit had maximum sustained winds near 52 mph and was stirring up rough surf and high waves along eastern Japan’s coastline. Extra-tropical storm Lupit was located approximately 580 nautical miles southwest of Tokyo, Japan, near 28.4 North and 134.8 East. It was moving northeast at 21 mph, and is expected to continue moving in that direction staying in open ocean. Lupit was completing transition to an extra-tropical storm and is also being adversely affected by wind shear (winds blowing at the storm in different levels of that atmosphere, that tear the storm apart). NASA’s Aqua satellite flew over both Lupit and TD23W on October 26 at 3:41 UTC (October 25 at 11:41 p.m. EDT).

The Atmospheric Infrared Sounder (AIRS) instrument on Aqua captured both a visible and infrared image of the storms. The infrared satellite image confirmed that all of Lupit’s deep convection (developing strong thunderstorms) has dissipated, and the most intense precipitation has shifted all to the northeast of the center of circulation, further exposing the center to wind shear. Meanwhile, the image also showed that 23W appeared to be getting well-organized.

Tropical Storm 23W had maximum sustained winds near 40 mph at 11 a.m. EDT on October 26. The storm’s center was about 200 nautical miles east of Guam, near 13.4 North and 147.7 East. It was moving west-northwest near 17 mph. NASA’s CloudSat satellite also flew over 23W earlier this morning.

CloudSat captured a side view of 23W’s clouds on Oct. 26 between 03:43 – 03:46 UTC. CloudSat revealed sustained winds of 27 mph and a minimum central pressure of 1002 millibars when it was centered near 122 North and 151.3 East. Sustained winds have since increased to 40 mph. CloudSat also showed some high, strong thunderstorm cloud tops over 14 kilometers (almost 9 miles) high. The forecast track from the JTWC takes Tropical Storm 23W between Andersen Air Force Base (island) and the island of Saipan, located north of Andersen. The storm is then forecast to intensify and move west toward the Philippines.

Reason to Name Hurricanes

Filed under: Future Hurricane Names, Hurricane History — admin @ 11:06 am
 

Experience shows that the use of short, distinctive names in written as well as spoken communications is quicker and less subject to error than the older, more cumbersome latitude-longitude identification methods. These advantages are especially important in exchanging detailed storm information between hundreds of widely scattered stations, coastal bases, and ships at sea.

The use of easily remembered names greatly reduces confusion when two or more tropical storms occur at the same time. For example, one hurricane can be moving slowly westward in the Gulf of Mexico, while at exactly the same time another hurricane can be moving rapidly northward along the Atlantic coast. In the past, confusion and false rumors have arisen when storm advisories broadcast from radio stations were mistaken for warnings concerning an entirely different storm located hundreds of miles away.

History of Hurricane Names

For several hundred years many hurricanes in the West Indies were named after the particular saint’s day on which the hurricane occurred. Ivan R. Tannehill describes in his book “Hurricanes” the major tropical storms of recorded history and mentions many hurricanes named after saints. For example, there was “Hurricane Santa Ana” which struck Puerto Rico with exceptional violence on July 26, 1825, and “San Felipe” (the first) and “San Felipe” (the second) which hit Puerto Rico on September 13 in both 1876 and 1928.

Tannehill also tells of Clement Wragge, an Australian meteorologist who began giving women’s names to tropical storms before the end of the l9th century.

An early example of the use of a woman’s name for a storm was in the novel “Storm” by George R. Stewart, published by Random House in 1941, and since filmed by Walt Disney. During World War II this practice became widespread in weather map discussions among forecasters, especially Air Force and Navy meteorologists who plotted the movements of storms over the wide expanses of the Pacific Ocean.

In 1953, the United States abandoned a confusing two-year old plan to name storms by a phonetic alphabet (Able, Baker, Charlie) when a new, international phonetic alphabet was introduced. That year, the United States began using female names for storms.

The practice of naming hurricanes solely after women came to an end in 1978 when men’s and women’s names were included in the Eastern North Pacific storm lists. In 1979, male and female names were included in lists for the Atlantic and Gulf of Mexico.
