As many November tropical cyclones do, it formed in the … The season featured a total of 31 (sub)tropical cyclones, all but one of which became a named storm. FILE - In this Sept. 12, 2018 photo provided by NASA, Hurricane Florence churns over the Atlantic Ocean heading for the U.S. east coast as seen from the International Space Station. MUR incorporates temperature data from multiple NASA, NOAA, and international satellites, as well as ship and buoy observations. These included warmer-than-average Atlantic sea surface temperatures and a stronger west African monsoon, along with much weaker vertical wind shear and wind patterns coming off of Africa that were more favorable for storm development. The National Oceanic and Atmospheric Administration (NOAA) GOES-16 satellite (one of many geostationary NOAA satellites developed and launched by NASA) captured a natural-color image on Nov. 16 at 10 a.m. local time when the storm was at its peak strength. [Written by NOAA] November 2020 was very warm and quite dry for the United States as the Atlantic’s extremely active hurricane season came to a close. In addition, it was the fifth consecutive above average Atlantic hurricane season from 2016 onward. 1 of 7. These two- and three-dimensional observations of precipitation structure are the hallmark of the GPM mission – managed jointly by NASA and the Japan Aerospace Exploration Agency (JAXA) — which aims improve our understanding of the water cycle and extreme weather events, and contributes to improved climate modeling and weather forecasting around the world. Additionally, three hurricanes — Isaias, Laura, and Sally — passed within range of NOAA’s hurricane ocean gliders this year, capturing invaluable ocean data below the storms while hurricane hunter planes captured atmospheric data above. (Credit: NOAA Satellites), This infographic highlights key facts and statistics from the 2020 Atlantic Hurricane Season (at the time of publishing on November 24). Iota reached Category 5 strength before making landfall as a Category 4 storm near the town of Haulover, Nicaragua. Iota developed on Nov. 13 and strengthened to a hurricane two days later. “As we correctly predicted, an interrelated set of atmospheric and oceanic conditions linked to the warm AMO were again present this year. By Michael Carlowicz, with scientific interpretation from Timothy Hall of the NASA Goddard Institute for Space Studies. The majority of hurricanes in Florida arrive in the months of September and October, and no major hurricane has ever hit the United States in November. According to Saffir-Simpson Hurricane Wind Scale, a major hurricane, Category 3 or higher, has winds beginning at 111 miles per hour. NASA’s Earth Applied Sciences Disasters Program supports disaster response and risk reduction efforts throughout the world — before, during, and after disasters strike – and is working to aid Central America with the impacts from these storms. Twitter . — Southern Alliance for Clean Energy (@cleanenergyorg) November 11, 2020 On Wednesday, scientists from the Okinawa Institute of Science and Technology published a new study in Nature that concluded: Within a day and a half, Iota’s wind speeds increased by 160 kilometers (100 miles) per hour. Climate change is causing hurricanes that make landfall to take more time to weaken, reports a study published 11th November 2020 in the journal … GPM observed the storm’s rainfall with its two unique science instruments: the GPM Microwave Imager (GMI) and Dual-frequency Precipitation Radar (DPR). It w… by Panopticon | Nov 23, 2020 | Climate | 0 comments. The season officially ends November 30. “Our investments in research, forecast models, and computer technology allowed forecasters at the National Weather Service, and its National Hurricane Center, to issue forecasts with increasing accuracy, resulting in the advanced lead time needed to ensure that decision makers and communities were ready and responsive.”. Iota is the strongest hurricane and 30th named storm of the 2020 Atlantic season, the most since modern record keeping began (breaking the previous record of 28 set in 2005.) Heavy rainfall from these two storm systems brought widespread flooding to the region, triggered large and numerous landslides in Guatemala and Honduras, and was responsible for numerous casualties. The onslaught of destructive winds and heavy rainfall was unfortunately familiar to a region that recently suffered another Category 4 landfalling storm – Hurricane Eta – just two weeks earlier. (NOAA National Weather Service), National Oceanic and Atmospheric Administration, Atlantic Oceanographic and Meteorological Laboratory, Track active weather with NOAA’s new radar viewer, Dr. Michael R. Farrar is new director of National Centers for Environmental Prediction. The 13 hurricanes and 6 major hurricanes in 2020 are both the second most on record behind 2005 (15 and 7, respectively). Iota is the 13th storm to reach hurricane strength this year; the average hurricane year brings six hurricanes. “Throughout this relentless hurricane season, NOAA worked around-the-clock to provide critical data and reliable forecasts to our Nation’s communities in the path of devastating storms,” said U.S. Secretary of Commerce Wilbur Ross. While the official hurricane season concludes on November 30, tropical storms may continue to … This vital oceanic data allowed forecasters to help mariners avoid dangerous situations at sea. 1 of 4. ESA Sentinel-2 data was also used to detect likely flooded areas at Honduras’ San Pedro Sula airport.  The Program can take the landslide and flood detection data, then combine it with openly available population data and road maps, and deliver actionable guidance to local decision makers on where to best direct their response efforts. Through November 30, and the official end of the Atlantic hurricane season, several records were tied or broken. Last month’s heat also added to a warm stretch so far for 2020, ranking the year to date as the nation’s fourth warmest, according to scientists at NOAA’s National Centers for Environmental Information (NCEI). The Atlantic hurricane season officially ends November 30, but storm activity in the tropics can sometimes continue beyond that date. Note: Satellite animation video runs from May 13 through November 18, 2020. Such active eras for Atlantic hurricanes have historically lasted about 25 to 40 years. These conditions, combined with La Nina, helped make this record-breaking, extremely active hurricane season possible,” said Gerry Bell, Ph.D, lead seasonal hurricane forecaster at NOAA’s Climate Prediction Center. One example is the landslide detection maps from the Semi-Automatic Landslide Detection (SALaD) project, which use machine learning to analyze data from commercial Planet Labs satellites and the European Space Agency (ESA) Copernicus Sentinel-2 satellite. Facebook. The extremely active 2020 Atlantic hurricane season is drawing to a close with a record-breaking 30 named storms and 12 landfalling storms in the continental United States. In total, the 2020 season produced 30 named storms (top winds of 39 mph or greater), of which 13 became hurricanes (top winds of 74 mph or greater), including six major hurricanes (top winds of 111 mph or greater).
