The south side of Tropical Storm Lowell appears to be its toughest side. That is, the side with the strongest thunderstorms, according to satellite imagery from NOAA's GOES-14 and NASA-NOAA's Suomi NPP satellites.
NOAA took its GOES-14 satellite out of storage to simulate how the upcoming GOES-R satellite will work and captured a lot of data on Tropical Storm Lowell on August 19.
Those data were used to create an animation that showed a gradual increase in the organization of a band of thunderstorms during the day.
The Visible Infrared Imaging Radiometer Suite (VIIRS) instrument that flies aboard NASA-NOAA's Suomi NPP satellite captured a visible image of Tropical Storm Lowell on August 19 at 21:42 UTC (5:42 p.m. EDT).
The image showed a thick band of thunderstorms southwest of the center of circulation, wrapping into the center.
At 5 a.m. EDT on Wednesday, August 20, the National Hurricane Center (NHC) noted that curved bands of thunderstorms remained well organized on the south side of the circulation, but strong showers and thunderstorms were lacking to the north of the center.
At the same time, the center of Tropical Storm Lowell was located near latitude 18.7 north and longitude 121.0 west. That's about 775 miles (1,245 km) west-southwest of the southern tip of Baja California. Maximum sustained winds remain near 50 mph (85 kph).
Lowell was moving toward the northwest near 5 mph (7 kph) and the NHC expects a slow northwest to north-northwest motion during the next day or so.
Forecaster Cangialosi at NHC noted that Lowell is currently over 27C/80.6F waters, and in an atmosphere of fairly low shear and high moisture. Tropical cyclones need waters at least near 26.6C/80F to maintain strength. Since the storm is expected to remain in these favorable conditions for another day and a half, some strengthening is forecast.

In the last decades, sea level has been rising continuously – about 3.3 mm per year. For reef islands such as the Maldives or the Marshall Islands a sinister picture is being painted evoking the demise of the island states and their cultures. Are the effects of sea-level rise already noticeable on reef islands? Scientists from the ZMT have now answered this question for the Takuu Atoll, a group of Pacific islands, located northeast of Papua New Guinea.

The ‘Internet of Things’ is growing rapidly. Mobile phones, washing machines and the milk bottle in the fridge: the idea is that minicomputers connected to these will be able to process information, receive and send data. This requires electrical power. Transistors that are capable of switching information with a single electron use far less power than field effect transistors that are commonly used in computers. However, these innovative electronic switches do not yet work at room temperature. Scientists working on the new EU research project ‘Ions4Set’ intend to change this. The program will be launched on February 1. It is coordinated by the Helmholtz-Zentrum Dresden-Rossendorf (HZDR).
