GOES-13's wide view of Atlantic's Tropical Storm Lisa and low, Pacific's Georgette

23.09.2010
The GOES-13 satellite may be stationed in orbit over the eastern U.S., but it has a wide field of view from the eastern Atlantic to the eastern Pacific, and today it captured three tropical cyclones in one image.

At 1445 UTC (10:45 a.m. EDT) today, Sept. 22, the Geostationary Operational Environmental Satellite called GOES-13 captured Tropical Storm Lisa in the far eastern Atlantic, a developing tropical low in the south-central Caribbean Sea, and Tropical Storm Georgette in the eastern Pacific Ocean, making landfall in Baja California. The GOES series of satellites are managed by NOAA, and NASA's GOES Project at NASA's Goddard Space Flight Center in Greenbelt, Md. creates images and animations from the satellite data.

Tropical Storm Lisa is struggling today in the eastern Atlantic Ocean because of wind shear and dry air. Lisa was producing a small area of deep convection near the surface of her center of her circulation. The center of circulation is also exposed to outside winds, which make the storm prime for weakening. In addition, there is a lot of dry air around Lisa at the middle levels of the troposphere (likely from the Saharan dust that has been blowing off the African coast). All of those things are indicators why Lisa has not been able to intensify.

The Tropical Rainfall Measuring Mission (TRMM) satellite passed above Lisa on Sept. 21 at 2309 UTC (7:09 p.m. EDT) and revealed a few areas of moderate to heavy thunderstorms with rain falling at about 2 inches per hour within the storm's circulation.

At 11 a.m. EDT on Sept. 22, Lisa had maximum sustained winds near 45 mph. The National Hurricane Center noted that some strengthening is possible over the next 48 hours, so the environmental conditions should become more conducive for the tropical cyclone. Lisa was 435 miles west of the Cape Verde Islands, near 17.1 North and 30.5 West. It was moving very little in a southeasterly direction at 3 mph and is forecast to move little in the next couple of days. Estimated minimum central pressure is 1002 millibars.

Meanwhile, there is a low pressure area in the south-central Caribbean Sea that forecasters are watching. Today's GOES-13 satellite image does show some circulation in the clouds associated with the low. NOAA's National Hurricane Center (NHC) noted that this low has the potential to become the 15th tropical depression of the Atlantic Ocean hurricane season over the next day or two. In fact, NHC gives the low a 60 percent chance of making the grade to tropical depression in 48 hours. That low is expected to bring showers and squalls over the Netherlands Antilles and the northern coasts of western Venezuela and Colombia today.

Further west, Tropical Depression Georgette has already crossed over Baja California and is now headed to another landfall on the mainland in Mexico. A tropical storm watch is in effect for the coast of mainland Mexico from Huatabampito Northward to Bahia Kino.

When the Tropical Rainfall Measuring Mission (TRMM) satellite passed over Georgette on Sept. 22 at 0344 UTC ( Sept. 21 11:44 p.m. EDT) the tropical depression had isolated moderate thunderstorms near the center with rainfall between .78 to 1.57 inches per hour.

Georgette is a tropical depression with maximum sustained winds near 35 mph. It is located in the Sea of Cortes (the Gulf of California) and is about 85 miles south of Guaymas, Mexico. It is centered near 26.8 North and 111.0 West, with a minimum central pressure of 1000 millibars.

The depression is moving toward the north-northwest near 14 mph and is expected to turn north later today making landfall tonight. The NHC noted that "Georgette is expected to produce total rainfall accumulations of 4 to 6 inches over the western portions of the state of Sonora with isolated maximum amounts of 10 inches possible."

Im Focus: Electron highway inside crystal

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.

Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...

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:...

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...
