NASA Satellites Capture Super-Typhoon Utor Before and After Landfall

13.08.2013
Four NASA satellites provided data on Super-Typhoon Utor before and after the storm made landfall in the Philippines.

Satellite imagery from NASA's Aqua, Terra, TRMM and CloudSat satellites captured information about the powerful Super-Typhoon on Aug. 11 and 12. That data was used by forecasters at the Joint Typhoon Warning Center before and after Utor hit the Philippines.

On Sunday, Aug. 11 at 0719 UTC (3:19 a.m. EDT) NASA's Tropical Rainfall Measuring Mission or TRMM satellite captured rates of heavy rainfall around the storm's center and western quadrant near 1.4 inches per hour. At that time, Utor's rainfall had already started spreading over the northern and central Philippines.

NASA's CloudSat satellite captured a sideways view of Super-Typhoon Utor that sliced through the storm's center on Aug. 11 just before the system hit the Philippines. Cloudsat revealed large amounts of liquid and ice water were abundant at middle and lower levels of the storm system, which were an indication of the storm's strength.

On Sunday, Aug. 11 at 1500 UTC (11 a.m. EDT), Utor's maximum sustained winds were near 130 knots/150mph/241 kph. It was centered just east of the Philippines near 15.7 north and 123.2 east. That's about 169 nautical miles east-northeast of Manila. Utor was moving to the west-northwest at 10 knots/11.5 mph/18.5 kph and headed for landfall.

In less than 13 hours, Super-Typhoon Utor's center crossed the Philippines and the storm weakened into a typhoon.

NASA's Terra satellite passed over the then weakened Typhoon Utor on Monday, Aug. 12 at 02:55 UTC (10:55 p.m. EDT/Aug. 11) as it was moving into the South China Sea. Utor had weakened to a typhoon after crossing the land and its center was near the Lingayen Gulf on the country's western side. Microwave and infrared satellite instrument imagery revealed an eye after Utor emerged over open water.

By 1500 UTC (11 a.m. EDT), Utor's center had already crossed over the Philippines from east to west and emerged in the South China Sea. Maximum sustained winds had dropped to 85 knots/97.8 mph/157.4 kph. Typhoon Utor was located approximately 346 nautical miles/398 miles/641 km southeastward of Hong Kong, near 17.9 north and 117.3 east and has tracked west-northwestward at 14 knots/16 mph/26 kph.

A large number of warnings in remain effect today, Aug. 12, as Typhoon Utor moves through the South China Sea and away from the Philippines. Public storm warning signal #1 is still in effect in the following provinces: Abra, Kalinga, Apayao, Isabela, Aurora, Quirino, Nueva Ecija, Tarlac, Ilocos Norte, Pampanga, Bataan and Zambales. Public storm warning signal #2 is in effect in the provinces of: Nueva Vizcaya, Ifugao, Mt. Province, Ilocos Sur, Benguet, La Union and Pangasinan.

Reuters News Service reported on Aug. 12 that one person died and there were at least 13 people missing. Reuters also noted that the hardest hit town was Casiguran in Aurora province on the Philippines' east coast. Casiguran is the unofficial capital of the northern part of Aurora and is well-known for its beaches and recreation. Utor caused power outages, agricultural damages and landslides.

After weakening over the Philippines, Utor is expected to re-strengthen in the South China Sea before making a final landfall in southeastern China. Forecasters at the Joint Typhoon Warning Center noted that the current track of the storm takes the center between Hainan Island, China and Hong Kong for a landfall on Aug. 14.

On Aug. 13 at 11:15 a.m. EDT (15:15 UTC), the Hong Kong Observatory issued Standby Signal, No. 1 which means that Utor is within 800 kilometers of Hong Kong.

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
