This special version of the 2021 Hurricane Season data visualization uses all the below layers to show the entire 2021 Hurricane Season, but elements of it were sped up in post production to accelerate the data when no hurricanes are present. This provides the viewer with a more compact experience that focuses exclusively on the hurricanes.
This visualization shows the hurricanes and tropical storms of 2021 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 laid under 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.
This data visualization shows the complete 2021 hurricane season beginning on May 1, 2021 throught November 30, 2021. Time moves at a constant rate throughout this visualization showing both the hurricanes and the down times between the hurricanes. After the last hurricane of the season, Wanda, is displayed, we dissolve in all the storms for the 2021 Hurricane season to show all their paths and strengths together on one map.
Surface Precipitation from May 1 through November 30, 2021 with time moving at a constant rate. Areas in green and yellow are areas of relatively light rain. Oranges and reds depict areas of intense rainfall.
