A nested-grid, basin-scale model of these phenomena called HWRF was retired in favor of HAFS (“H-A-F-S”) in 2023. Infrared remote sensing is used to identify these phenomena with patterns such as the curved band or the central cold cover, which correspond to different ranges of T-numbers in the Dvorak (“d’VOR-ack”) technique. These phenomena are monitored in seven basins, out of which only Australia measures their intensity over ten minutes rather than one minute. (10[1])Close-range interactions between two of these phenomena are named after Fujiwhara. (10[2]-5[2])NOAA's mesoscale models rate these phenomena by their maximum sustained winds. (10[1])These phenomena are measured on the five-category Saffir–Simpson (10[1])scale. For 10 points, name these weather phenomena that rotate around a low-pressure “eye.” ■END■ (10[1])
