This image was taken by TEMPEST-D (Temporal Experiment for Storms and Tropical Systems Demonstration) as it flew over Hurricane Florence on Sept. 11, 2018. The colors reveal the eye of the storm, surrounded by towering, intense rain bands. The green areas highlight the extent of the rain being produced by the storm, with the most intense rain shown in the yellow and red areas. The black and white image underneath is a visual image of the storm's clouds, taken by NOAA's GOES (Geoweather Operational Environmental Satellite). Credits: NASA/NOAA/Naval Research Laboratory Monterey/JPL-Caltech A new experimental weather satellite no bigger than a cereal box got an inside look at Hurricane Florence in a test of technology that could influence the future of storm monitoring from space. The satellite took its first images of Hurricane Florence on Tuesday, Sept. 11, just hours after its instrument was turned on. TEMPEST-D, which deployed into low-Earth orbit from the International Space Station in July, carries a state-of-the-art miniaturized microwave radiometer, an instrument that sees through the thick clouds to reveal the hidden interior of storms, just like a security scanner can see inside luggage at the airport.

Screenshot of the CAMP2Ex web portal interface. The CAMP2Ex portal (https://camp2ex.jpl.nasa.gov) was developed to support the upcoming NASA’s CLOUD AND AEROSOL MONSOONAL PROCESSES - PHILIPPINES EXPERIMENT (CAMP2Ex). The portal monitors hurricanes and tropical convection in the West Pacific and the Indian ocean basins. It provides interactive visualization, data integration and on-line analysis tools. The portal: i) integrates model forecasts with satellite and airborne observations from a variety of instruments and platforms, allowing for easy model/observations comparisons; ii) Allows interrogation of a large number of atmospheric and ocean variables to better understand the large-scale and storm-scale processes associated with tropical convection. This NASA-funded system (CAMP2Ex, ESTO/AIST) provides very rich information for near-real time and post-hurricane analyses to support research of tropical convection.

Video of 7-Day Animation of Mangkhut Affecting the Philippines In the past week, Typhoon Mangkhut has affected the Philippines, mainland China, and Hong Kong, as shown in this 7-day animation of NASA's satellite-based IMERG precipitation product. The upper frame shows the storm-total accumulation starting at 0100 UTC on September 11, 2018. Storm-total accumulations in excess of 4 inches stretched from Manila to the northern tip of Luzon Island where the rainfall triggered deadly landslides. The lower frame shows the short-term accumulation in a 3-hour period that slides from the beginning to the end of the 7-day-long movie. The sliding 3-hour accumulation clearly shows how Mangkhut's compact eyewall prior to its Philippines landfall was replaced by a much larger, ragged eyewall thereafter. In some cases, interactions with mountainous islands greatly reduce a tropical cyclone's rainfall, but in this case, Typhoon Mangkhut was too powerful to succumb to these mountain interactions.

Having churned through the Atlantic for two weeks, Hurricane Florence is among the longest-lived cyclones of the 2018 season. That means the storm’s winds have had plenty of time to rage and ease as they ran into different environmental conditions over the Atlantic Ocean. This animation highlights the storm’s wind field between September 1 and September 14, 2018. The strongest winds appear red; weaker winds are white. The wind data comes from the Goddard Earth Observing System Model (GEOS), an experimental weather model that scientists at NASA use to analyze global weather phenomena. The GEOS model ingests wind data from more than 30 sources, including ships, buoys, radiosondes, dropsondes, aircraft, and satellites.

Look: https://t.co/6uqdmdVMns pic.twitter.com/a1nkk96zIr — NASA (@NASA) September 15, 2018 Florence emerged off the west coast of Africa near Cape Verde on September 1. As the tropical storm drifted west, it slowly intensified until achieving hurricane status on September 4 with peak winds of 75 miles (120 kilometers) per hour. By tradition, meteorologists use the Saffir-Simpson scale to categorize hurricane intensity. Category 1 hurricanes have winds of between 74 and 95 miles (119 and 153 kilometerss) per hour; Category 5 storms, the highest on the scale, have winds that surpass 157 miles (252 kilometers) per hour.
