NASA Catches the Eye of Typhoon Lingling 5 September 2019
NASA catches the eye of Typhoon Lingling 5 September 2019 Warning Center or JTWC said that Typhoon Lingling, known locally in the Philippines as Liwayway, had moved away from the Philippines enough that warnings have been dropped. Lingling was located near 23.0 degrees north latitude and 125.4 degrees east longitude. That is 247 nautical miles southwest of Kadena Air Base, Okinawa, Japan. Lingling was moving to the north- northeast and maximum sustained winds had increased to near 80 knots (75 mph/120.3 kph). JTWC forecasters said that Lingling is moving north and is expected to intensify to 105 knots (121 mph/194 kph) upon passing between Taiwan and Japan. Provided by NASA's Goddard Space Flight Center On Sept. 4, 2019 at 1:20 a.m. EDT (0520 UTC) the MODIS instrument that flies aboard NASA's Terra satellite showed powerful thunderstorms circling Typhoon Lingling's visible eye. Credit: NASA/NRL Typhoon Lingling continues to strengthen in the Northwestern Pacific Ocean and NASA's Terra satellite imagery revealed the eye is now visible. On Sept. 4 at 1:20 a.m. EDT (0520 UTC) the Moderate Imaging Spectroradiometer or MODIS instrument that flies aboard NASA's Terra satellite showed powerful thunderstorms circling Typhoon Lingling's visible 15 nautical-mile wide eye. The Joint Typhoon Warning Center (JTWC) noted, "Animated enhanced infrared satellite imagery depicts tightly-curved banding wrapping into a ragged eye." In addition, microwave satellite imagery showed a well-defined microwave eye feature.

SST drops 4 of a few degrees in the open ocean after typhoon passages have been widely documented; 5 however, few studies have focused on coastal SST variability. The purpose of this study is to 6 determine typhoon-induced SST drops in the near-coastal area (within 1 km of the coast) and 7 understand the possible mechanism. The results of this study were based on extensive field data 8 analysis. Significant SST drop phenomena were observed at the Longdong buoy in northeastern 9 Taiwan during 43 typhoons over the past 20 years (1998~2017). The mean SST drop (∆SST) 10 after a typhoon passage was 6.1 °C, and the maximum drop was 12.5 °C (Typhoon Fungwong 11 in 2008). -
Global Catastrophe Review – 2015
GC BRIEFING An Update from GC Analytics© March 2016 GLOBAL CATASTROPHE REVIEW – 2015 The year 2015 was a quiet one in terms of global significant insured losses, which totaled around USD 30.5 billion. Insured losses were below the 10-year and 5-year moving averages of around USD 49.7 billion and USD 62.6 billion, respectively (see Figures 1 and 2). Last year marked the lowest total insured catastrophe losses since 2009 and well below the USD 126 billion seen in 2011. 1 The most impactful event of 2015 was the Port of Tianjin, China explosions in August, rendering estimated insured losses between USD 1.6 and USD 3.3 billion, according to the Guy Carpenter report following the event, with a December estimate from Swiss Re of at least USD 2 billion. The series of winter storms and record cold of the eastern United States resulted in an estimated USD 2.1 billion of insured losses, whereas in Europe, storms Desmond, Eva and Frank in December 2015 are expected to render losses exceeding USD 1.6 billion. Other impactful events were the damaging wildfires in the western United States, severe flood events in the Southern Plains and Carolinas and Typhoon Goni affecting Japan, the Philippines and the Korea Peninsula, all with estimated insured losses exceeding USD 1 billion. The year 2015 marked one of the strongest El Niño periods on record, characterized by warm waters in the east Pacific tropics. This was associated with record-setting tropical cyclone activity in the North Pacific basin, but relative quiet in the North Atlantic. -

Hurricane & Tropical Storm
5.8 HURRICANE & TROPICAL STORM SECTION 5.8 HURRICANE AND TROPICAL STORM 5.8.1 HAZARD DESCRIPTION A tropical cyclone is a rotating, organized system of clouds and thunderstorms that originates over tropical or sub-tropical waters and has a closed low-level circulation. Tropical depressions, tropical storms, and hurricanes are all considered tropical cyclones. These storms rotate counterclockwise in the northern hemisphere around the center and are accompanied by heavy rain and strong winds (NOAA, 2013). Almost all tropical storms and hurricanes in the Atlantic basin (which includes the Gulf of Mexico and Caribbean Sea) form between June 1 and November 30 (hurricane season). August and September are peak months for hurricane development. The average wind speeds for tropical storms and hurricanes are listed below: . A tropical depression has a maximum sustained wind speeds of 38 miles per hour (mph) or less . A tropical storm has maximum sustained wind speeds of 39 to 73 mph . A hurricane has maximum sustained wind speeds of 74 mph or higher. In the western North Pacific, hurricanes are called typhoons; similar storms in the Indian Ocean and South Pacific Ocean are called cyclones. A major hurricane has maximum sustained wind speeds of 111 mph or higher (NOAA, 2013). Over a two-year period, the United States coastline is struck by an average of three hurricanes, one of which is classified as a major hurricane. Hurricanes, tropical storms, and tropical depressions may pose a threat to life and property. These storms bring heavy rain, storm surge and flooding (NOAA, 2013). The cooler waters off the coast of New Jersey can serve to diminish the energy of storms that have traveled up the eastern seaboard. -
GPM Satellite Finds Sheared Hurricane Jose Has Very Tall Storms 14 September 2017, by Rob Gutro
GPM satellite finds sheared Hurricane Jose has very tall storms 14 September 2017, by Rob Gutro meandering in the Atlantic Ocean. GPM found that even though Jose was affected by strong northwesterly shear, it contained very powerful convective storms. GPM's Dual-Frequency Precipitation Radar (DPR) found extremely intense downpours within these storms where rain was measured by DPR falling at a rate of over 8.9 inches (227 mm) per hour. At NASA's Goddard Space Flight Center in Greenbelt, Maryland, GPM's radar (DPR Ku Band) was used to create a 3-D cross-section of the precipitation within hurricane Jose. This 3-D examination by DPR showed that some of the powerful convective storms within Jose had tops that were reaching altitudes greater than 10.85 miles (175 km). GPM is a joint mission of NASA and the Japan Aerospace Exploration Agency, JAXA. NASA's Aqua Satellite View On Sept. 14 at 1:50 p.m. EDT (17:50 UTC) the Moderate Resolution Imaging Spectroradiometer aboard NASA's Aqua satellite captured a visible image of Hurricane Jose that continued to show the storm was being affected by vertical wind shear as On Sept. 14 at 1:50 p.m. EDT (17:50 UTC) NASA's the storm appeared somewhat elongated from Aqua satellite captured this image of Hurricane Jose that northwest to southeast. continued to show the storm was being affected by vertical wind shear.

This study developed a fast storm surge ensemble prediction method based on TC track probability forecasting and searching optimization of a numerical scenario database (SONSD). In a case study of the Fujian Province coast (China), a storm surge scenario database was established using numerical simulations generated by 93 150 hypothetical TCs. In a GIS-based visualization system, a single surge forecast representing 2562 distinct typhoon tracks and the occurrence probability of overflow of seawalls along the coast could be achieved in 1–2 min. Application to the cases of Typhoon Soudelor (2015) and Typhoon Maria (2018) demonstrated that the proposed method is feasible and effective. Storm surge calculated by SONSD had excellent agreement with numerical model results (i.e., mean MAE and RMSE: 7.1 and 10.7 cm, respectively, correlation coefficient: .0.9). -
