    2020 Hurricane Season

    Feb. 25th, 2021
    (updated Aug. 25th, 2023)

    Data visualization of the 2020 Hurricane Season. Starts on May 1, 2020 just showing Sea Surface Temperatures and cloud cover. Precipitation data then dissolves in as hurricanes are tracked throughout 2020. Hurricane tracks include Hurricane strengths depicted with the letter "T" for Tropical Storm and numbers for each storm's respective strength. The visualization then culminates by showing all the storm tracks at once.This video is also available on our YouTube channel. || The 2020 Atlantic hurricane season smashed records with an unprecedented 30 named storms, marking the fifth year in a row with above-average hurricane activity. The National Weather Service noted that every mile of the U.S. Atlantic coast was under a tropical watch or warning in 2020. NOAA reported the most billion-dollar disasters in the U.S. in a single year in the 40 years of record-keeping, with significant contributions from the five storms that made landfall in the U.S.This visualization shows the hurricanes and tropical storms of 2020 as seen by NASA’s Integrated Multi-satellitE Retrievals for GPM (IMERG) - a data product combining precipitation observations from infrared and microwave satellite sensors united by the GPM Core Observatory. IMERG provides near real-time half-hourly precipitation estimates at ~10km resolution for the entire globe, helping researchers better understand Earth’s water cycle and extreme weather events, with applications for disaster management, tracking disease, resource management, energy production and food security. IMERG rain rates (in mm/hr) are overlaid on infrared cloud data from the NOAA Climate Prediction Center (CPC) Cloud Composite dataset together with storm tracks from the NOAA National Hurricane Center (NHC) Automated Tropical Cyclone Forecasting (ATCF) model. Sea surface temperatures (SST) are also shown over the oceans, derived from the NASA Multi-sensor Ultra-high Resolution (MUR) dataset, which combines data from multiple geostationary and orbiting satellites. Sea surface temperatures play an important role in hurricane formation and development, with warmer temperatures linked to more intense storms. 2020 was the warmest year on record, and this year’s hurricane season brought many examples of storms that intensified quickly: ten of the 30 named storms showed rapid intensification. ||

    NASA captures Isaias bringing heavy rains to the Northern Bahamas

    Aug. 4th, 2020
    (updated Aug. 25th, 2023)

    GPM captured Tropical Storm Isaias off the coast of Florida as it pounded the Northern Bahama Islands on August 2nd, 2020.This video is also available on our YouTube channel. || After forming into a tropical storm in the eastern Caribbean, Isaias crossed over Hispaniola and back into the western Atlantic heading northwest towards the Bahamas. During this time, Isaias strengthened into a Category 1 hurricane before then passing through the southern and central Bahamas. As it crossed Andros Island in the central Bahamas, Isaias also came under the effects of southwesterly wind shear, which together with the land interaction caused it to weaken back to a strong tropical storm. This animation follows Isaias into the central Bahamas using NASA’s IMERG rainfall product. With IMERG, precipitation estimates from the GPM core satellite are used to calibrate precipitation estimates from microwave and IR sensors on other satellites to produce half-hourly precipitation maps at 0.1 degree horizontal resolution. After it crossed Andros Island, Isaias was overflown by the GPM core satellite itself at 09:11 UTC (5:11 am EDT) on the morning of Sunday August 2nd, which is detailed in the second part of the animation. Here rainfall rates derived directly from the GPM Microwave Instrument (or GMI) and Dual-Polarization Radar (or DPR) provide a detailed look into Isaias. GPM shows a large area of heavy rain (shown in red) covering the northern Bahamas. GPM also shows that this rain is located almost entirely northeast of Isaias’ center with very little rain on the western side of the storm. This highly asymmetric structure reflects both the effects of the wind shear as well as Isaias’ lack of intensity and hence ability to wrap precipitation around to the western side of the circulation. At the time of the GPM overpass, Isaias’ maximum sustained winds were reported at 65 mph by the National Hurricane Center, making it a strong tropical storm. Isaias would go onto regain hurricane intensity due to the warm waters of the Gulf Stream before making landfall on the southern coast of North Carolina.GPM data is archived at https://pps.gsfc.nasa.gov/ ||

    NASA Captures Isaias Twice Along the East Coast

    Aug. 5th, 2020
    (updated May 3rd, 2023)

    Music: "Seven Wonders," Universal Production Music || After forming into a tropical storm in the eastern Caribbean, Isaias crossed over Hispaniola and back into the western Atlantic heading northwest towards the Bahamas. During this time, Isaias strengthened into a Category 1 hurricane before then passing through the southern and central Bahamas. As it crossed Andros Island in the central Bahamas, Isaias also came under the effects of southwesterly wind shear, which together with the land interaction caused Isais to weaken back to a strong tropical storm. After regaining hurricane intensity over the Gulf Stream, Hurricane Isaias made landfall on the south coast of North Carolina on Monday August 3rd at 11:10 pm EDT near Ocean Isle Beach. This animation shows Isaias as is makes its way northward from the Bahamas to the coast of North Carolina using NASA’s IMERG rainfall product. With IMERG, precipitation estimates from the GPM core satellite are used to calibrate precipitation estimates from microwave and IR sensors on other satellites to produce half-hourly precipitation maps at 0.1-degree horizontal resolution. After making landfall, Isaias continued tracking northward over eastern North Carolina in response to a large upper-level trough located over the eastern half of the US. ||
