NASA sees organizing tropical low pressure area near the Philippines

A low pressure system in the western North Pacific has caught the eye of forecasters and several satellites as it continues to organize. NASA's Terra satellite captured a view of System 93W's clouds as they continue to appear more organized.

System 93W appears poised to become tropical storm Saola over the next two days if the organization continues. At 1400 UTC (10 a.m. EDT/U.S.; 10 p.m. Asia/Manila local time) System 93W had maximum sustained winds near 20 knots (23 mph/37 kmh). It was located about 395 nautical miles (454.6 miles/731.5 km) east-southeast of Manila, the Philippines, near 12.7 North latitude and 127.6 East longitude.

When NASA's Terra satellite passed over System 93W on July 27, 2012 at 10:14 p.m. (local time/Manila, Philippines) the center of the low appeared almost cloud-free, while broken bands of thunderstorms appeared to surround it from north to west to south.

When NASA's Terra satellite passed overhead on July 27, 2012 at 1414 UTC (10:14 a.m. EDT/U.S.; 10:14 p.m. local time/Manila, Philippines) the Moderate Resolution Spectroradiometer (MODIS) instrument captured an infrared image of the low pressure area. The center of the low appeared almost cloud-free, while broken bands of thunderstorms appeared to surround it from north to west to south. The northeastern side of the storm appeared to be lacking in clouds.

The Joint Typhoon Warning Center noted that "upper level analysis indicates the vertical wind shear has weakened as the storm motion became in-phase with the upper level winds." Weaker wind shear enables a low pressure area to strengthen, because it is not being battered by outside winds. In addition, sea surface temperatures are warm enough to contribute to the formation of a tropical depression (over 26.6 Celsius/80 Fahrenheit).

As a result of the weaker wind shear and improved banding of thunderstorms around the low's center, the Joint Typhoon Warning Center gave System 93W a "high chance" for becoming a tropical depression over the weekend of July 28-29.

Meanwhile, another low pressure system in the western North Pacific has a medium chance for development into a tropical depression. That low is located about 360 nautical miles (414 miles/666.7 km) east of Iwo-To, Japan, near 24.3 North and 147.8 East. On July 27, the showers and thunderstorms were being pushed to the east of the center due to wind shear.

Im Focus: Radar for navigation support from autonomous flying drones

At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.

Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
