NASA Satellites Calling Here You Come Again, Tropical Storm Dolly


Tropical Storm Dolly visited Mexico six years ago, and NASA satellite data is calling "Here you come again," reminiscent of the famous country singer's hit song, as another storm named Dolly heads for a second landfall in Mexico. 

In July of 2008, Tropical Storm Dolly made landfall on Mexico's Yucatan Peninsula of Mexico before making a second and final landfall in south Texas. Now, six years later, Tropical Storm Dolly returns thanks to the six year list of revolving hurricane names, and once again Dolly is making landfall in eastern Mexico. NASA's Aqua satellite caught Dolly developing over the Yucatan and poised for a second landfall in eastern Mexico today, September 2. 

On Sept. 1 at 12:45 p.m. EDT NASA's Terra satellite caught this image of the low pressure area that would become Tropical Storm Dolly, while it was moving over the Yucatan Peninsula.

On Sept. 1 at 12:45 p.m. EDT NASA's Terra satellite caught an image of the low pressure area that would become Tropical Storm Dolly, while it was moving over the Yucatan Peninsula.  By September 2, the low developed into a tropical storm.  The image, taken by the Moderate Resolution Imaging Spectroradiometer or MODIS instrument, showed the low pressure area as somewhat shapeless as it passed over the Yucatan. Once it slid west and entered the warm waters of the Bay of Campeche, it began to develop more.

An animation of visible and infrared satellite imagery from NOAA's GOES-East satellite was created by the NASA/NOAA GOES Project at NASA's Goddard Space Flight Center in Greenbelt, Maryland. The animation showed the birth and movement of Dolly from August 31 to September 2.  On August 31, Dolly was not yet named and was a low pressure area from the western Caribbean Sea that moved over the Yucatan Peninsula. The animation shows the development of the storm as the low moved across the Bay of Campeche. 

The Atmospheric Infrared Sounder or AIRS instrument aboard NASA's Aqua satellite captured infrared data on Tropical Storm Dolly on Sept. 2 at 3:59 a.m. EDT as it neared the east coast of Mexico. The data was made into a false-colored image at NASA's Jet Propulsion Laboratory in Pasadena, California. The AIRS image showed the strongest thunderstorms were on the eastern side of the center of circulation, where cloud tops stretched toward the top of the troposphere. Cloud tops in that area were as cold as -63F/-52C, indicative of high, strong thunderstorms. NASA research shows that thunderstorms with cloud top temperatures that cold have the potential for dropping heavy rainfall.

By September 2 at 8 a.m. EDT (1200 UTC) the center of Tropical Storm Dolly was located near latitude 23.0 north and longitude 95.7 west. That puts Dolly's center about 145 miles (230 km) east-southeast of la Pesca, Mexico. Dolly was moving toward the west-northwest near 13 mph (20 kph) and the center of the storm is expected to approach the coast by tonight, September 2, and move inland tomorrow. 

Maximum sustained winds have increased to near 50 mph (85 kph) and the National Hurricane Center (NHC) noted that some strengthening is possible until Dolly makes landfall. Tropical-storm-force winds extend outward up to 115 miles (185 km) mostly northeast through southeast of the center.

A tropical storm warning is in force from Tuxpan to Barra el Mezquital. The NHC noted that rainfall totals of 3 to 6, locally up to 10 inches are possible in southern Tamaulipas, northern Veracruz and eastern San Luis Potosi. Those heavy rains will likely cause flash flooding and mudslides in regions of mountainous terrain and that threat will continue as Dolly moves inland.

Im Focus: Climate study finds evidence of global shift in the 1980s

Planet Earth experienced a global climate shift in the late 1980s on an unprecedented scale, fuelled by anthropogenic warming and a volcanic eruption, according to new research published this week.

Scientists say that a major step change, or ‘regime shift’, in the Earth’s biophysical systems, from the upper atmosphere to the depths of the ocean and from...

Im Focus: Lactate for Brain Energy

Nerve cells cover their high energy demand with glucose and lactate. Scientists of the University of Zurich now provide new support for this. They show for the first time in the intact mouse brain evidence for an exchange of lactate between different brain cells. With this study they were able to confirm a 20-year old hypothesis.

In comparison to other organs, the human brain has the highest energy requirements. The supply of energy for nerve cells and the particular role of lactic acid...

Im Focus: Laser process simulation available as app for first time

In laser material processing, the simulation of processes has made great strides over the past few years. Today, the software can predict relatively well what will happen on the workpiece. Unfortunately, it is also highly complex and requires a lot of computing time. Thanks to clever simplification, experts from Fraunhofer ILT are now able to offer the first-ever simulation software that calculates processes in real time and also runs on tablet computers and smartphones. The fast software enables users to do without expensive experiments and to find optimum process parameters even more effectively.

Before now, the reliable simulation of laser processes was a job for experts. Armed with sophisticated software packages and after many hours on computer...
