Cyclone Bondoとは 意味・読み方・使い方

Intense Tropical Cyclone Bondo was a very strong tropical cyclone that was the first of a series of five cyclones to impact Madagascar during the 2006–07 South-West Indian Ocean cyclone season. Originating from an area of low pressure, associated with developing convection, on December 14, the precursor to Bondo initially tracked south-westward into a region of low wind shear and warm sea surface temperatures. Once in this region, the system began to quickly intensify, becoming a tropical storm on December 18. Throughout the day, the storm underwent an extreme period of rapid deepening known as explosive intensification. By the afternoon of December 19, Bondo attained its peak intensity with winds of 205 km/h (125 mph 10-minute sustained) and a barometric pressure of 930 hPa (mbar) according to Météo-France. At the same time, the Joint Typhoon Warning Center assessed the storm to have attained an intensity equivalent to a high-end Category 4 hurricane on the Saffir–Simpson Hurricane Scale with winds of 250 km/h (155 mph 1-minute sustained).
