The knot (/ n ɒ t /) is a unit of speed equal to one nautical mile per hour, exactly 1.852 km/h (approximately 1.151 mph or 0.514 m/s). [1] [2] ...
A tropical depression is a tropical cyclone that reaches maximum sustained winds below 34 knots (39 mph; 63 km/h). The Japan Meteorological Agency (JMA) is the main weather forecasting agency in the Pacific Northwest Pacific basin, where it measures sustained winds by averaging wind speeds in a period of ten minutes.
The category of a very strong typhoon is defined as a tropical cyclone that has 10-minute sustained wind speeds between 85 and 104 knots (157–193 km/h; 97–121 mph) or greater. Background [ edit ]
Since 1947, the Joint Typhoon Warning Center (JTWC) has classified all typhoons in the Northwestern Pacific Ocean with wind speeds of at least 130 knots (67 m/s; 150 mph; 241 km/h)—the equivalent of a strong Category 4 on the Saffir-Simpson scale, as super typhoons.
As the aircraft approached the airport, the wind changed from 210 degrees at 8 knots (9.2 mph; 14.8 km/h; 4.1 m/s) to 180 degrees at 7 knots (8.1 mph; 13.0 km/h; 3.6 m/s), but was reported as 270 degrees at 10 knots (11.5 mph; 18.5 km/h; 5.1 m/s). The aircraft became unstable and a go-around was executed. The flight returned for a visual ...
Typhoon Haiyan (Yolanda) on November 7, 2013, one of the strongest Pacific typhoons ever recorded.. Since 1947, the Joint Typhoon Warning Center (JTWC) has classified all typhoons in the Northwestern Pacific Ocean with wind speeds of at least 130 knots (67 m/s; 150 mph; 240 km/h)—the equivalent of a strong Category 4 on the Saffir–Simpson scale, as super typhoons.

In February 2019, the Navy awarded the ... Maximum speed is 8 knots (15 km/h), though the typical service speed is about 3 knots (5.6 km/h), which gives the Orca a ...
TAS can be calculated as a function of Mach number and static air temperature: =, where is the speed of sound at standard sea level (661.47 knots (1,225.04 km/h; 340.29 m/s)),
