Tropical Cyclone Ului's cold thunderstorm cloud tops using infrared imagery on March 17 at 10:35 a.m. EDT after the storm had departed the Solomon Islands..

Tropical Cyclone Ului has been almost sitting still in the Coral Sea for the last couple of days, but is once again moving and headed for a landfall in northeastern Queensland, Australia by the weekend.

The Atmospheric Infrared Sounder (AIRS) instrument on NASA's Aqua satellite captured Tropical Cyclone Ului's cold thunderstorm cloud tops on March 17 at 10:35 a.m. EDT (14:35 UTC) after the storm had departed the Solomon Islands. The infrared imagery revealed that the two strongest areas where convection was strongest in Ului were in the northern and southern areas around the eye.

It is in those two areas that the highest, coldest thunderstorm tops were revealed by AIRS infrared imagery. Those thunderstorm cloud tops were as cold as -63 Fahrenheit, and were areas where heavy rain was falling.

Low 17P Has a Good Chance for Tropical Reformation This Weekend

The Joint Typhoon Warning Center is the forecast center that issues advisories for tropical cyclones in the Southern Pacific Ocean, and they noted on February 26, "Available data does not justify issuance of numbered tropical cyclone warnings at this time" That may change over the weekend, as maximum sustained winds are near tropical depression strength, 34 mph (30 knots) and environmental factors are looking more favorably for further development.

Thursday, February 25, 2010

Tropical cyclone 17P may be a low pressure area right now, but environmental conditions have become more favorable to give it a likely comeback as a tropical storm. Forecasters are using satellite imagery and observing various factors to see if 17P may be reborn.

When the Geostationary Operational Environmental Satellite known as GOES-11 flew over 17P's center on Feb. 25 at 1622 UTC (11:22 a.m. ET), it captured in infrared image of its clouds. The satellite image showed that the storm appears to be getting re-organized, as seen in the circular shape of its clouds.

Wednesday, February 24, 2010

17P low on Feb. 24 at 0709 UTC (2:09 a.m. ET). The rainfall was scattered around the low’s center. The yellow and green areas indicate moderate rainfall between .78 to 1.57 inches per hour. The small red area indicates heavy rainfall at almost 2 inches per hour.

Monday, February 22, 2010

On February 21, the seventeenth tropical depression formed in the South Pacific Ocean. Today, February 22, the storm has strengthened into Tropical Storm 17P (TS 17P) with maximum sustained winds near 39 mph, and it was about 740 miles east-northeast of Pago Pago.

Fami on Feb. 3 at 09:35 UTC (4:35 a.m. ET), and showed the system more resembling a cold front than a tropical cyclone, as it appears stretched out from northwest to southeast. There are also very few strong thunderstorms left in what was once the center.

The Joint Typhoon Warning Center issued their last advisory on the system at 1 p.m. ET on February 2 after it crossed Madagascar, and entered the Southern Indian Ocean. At that time it was located approximately 150 nautical miles southwest of Antananarivo, Madagascar, near 21.0 South and 45.5 East. It had maximum sustained wind near 34 mph, but was rapidly fading. Fami tracked eastward at 11 mph (10 knots) into open waters.

Tuesday, February 02, 2010

February 1 at 2231 UTC (5:31 p.m ET) as it was approaching landfall in Madagascar. Heavy rain was falling from high thunderstorm cloud tops that were as cold as minus 63F.

image reveals that once Fami made landfall, the storm was developing an eye (blue) in the upper levels of the storm.

GOES-11 captured an infrared look at Oli’s clouds on Feb.1 at 1652 UTC (11: 52 a.m. ET). The storm appears to be well-defined.

The twelfth tropical cyclone in the Southern Pacific Ocean has formed today, February 1, 2010, and because of its proximity to the Fiji islands, it has been dubbed “Oli.” The GOES-11 satellite passed over Oli early this morning and captured an infrared image of the storm’s clouds.

GOES-11, or the Geostationary Operational Environmental Satellite, is operated by the National Oceanic and Atmospheric Administration and provides visible and infrared satellite imagery. Some of the imagery is created through the NASA GOES Project at NASA’s Goddard Space Flight Center in Greenbelt, Md. GOES-11 flew over Oli at 11:52 a.m. ET today, February 1, and noticed a well-organized tropical storm.

Oli’s name may also be referred to as Tropical Cyclone 12P in the news. The Fiji islands have their own list of tropical cyclone names, which may be confusing, because the Joint Typhoon Warning Center will typically use the number of the storm. The Joint Typhoon Warning Center is currently referring to Oli as “12P” for the twelfth tropical cyclone in the Southern Pacific Ocean.

At 10 a.m. ET, February 1, Tropical Storm Oli (12P) had maximum sustained winds near 57 mph (50 knots) up from 40 mph from 12 hours ago. Oli is moving east at 23 mph (20 knots). It was located about 540 nautical miles north-northwest of Rarotonga, near 13.5 degrees South and 162.9 degrees West.

Friday, January 29, 2010

NASA’s Aqua satellite passed over Olga at 11:29 p.m. EST Jan. 28 and the AMSR-E instrument measured the winds on Olga’s eastern side to be around 34 mph or 30 knots (in red), just before she strengthened back to tropical storm status.
