Although a tornado can have 74 mph winds there are many things that can have 74 mph winds and fast that are not tornadoes.
winds that are at least 74 mph are considered hurricane force though they can occur outside of hurricanes as well.
Winds of 74 mph or greater are called hurricane force winds. Note, though that this is not the same thing as a hurricane, which has a more specific definition.
It depends. If it is an organized system and the winds are sustained at 74 mph, then it is a hurricane. However, other wind storms can produce such winds as well.
That would most likely be the jet-stream.

The moon is far beyond the earth's atmosphere. The boundary between the atmosphere and outer space is generally considered to be an altitude of 62 miles, although there is a noticeable effect on spacecraft as high as 75 miles. The average distance from the earth to the moon is 233,000 miles.
1) (4-12 miles high)The troposphere is the first layer above the surface and contains half of the Earth's atmosphere. Weather occurs in this layer. 2) (31 miles high)Many jet aircrafts fly in the stratosphere because it is very stable. Also, the ozone layer absorbs harmful rays from the Sun. 3) (53 miles high)Meteors or rock fragments burn up in the mesosphere. 4) (430 miles high)The Thermosphere is a layer with auroras. It is also where the space shuttle orbits. 5) (6,200 miles high)The atmosphere merges into space in the extremely thin exosphere. This is the upper limit of our atmosphere.
If you have taped a straw to a balloon stretched over a jar top as a simple barometer, when the straw moves up, this is a sign of high pressure (atmosphere pressing down on the balloon). High pressure usually means fine weather.
The Karman Line, 100 km (62 miles) above the surface of the earth, is usually regarded as the boundary between the earth's atmosphere and outer space.The earth's atmosphere has many layers:Magnetosphere - the highest layerExosphere (500 to 1000 km altitude)Thermosphere (including ionosphere and the Karman Line, 100 km up, which is the boundary between the atmosphere and outer space.MesosphereStratosphere (including ozone layer, 15 to 35 km high)Troposphere (including peplosphereor planetary boundary layer) - the lowest layer, whose depth is 17 km (11 miles) at the equator and 7 km (5 miles) at the poles.
Wind is the result of differences in pressure in the atmosphere and flows between air masses. It moves from high-pressure to low-pressure regions, in an attempt to even out all different barometric pressures.
The moon is far beyond the earth's atmosphere. The boundary between the atmosphere and outer space is generally considered to be an altitude of 62 miles, although there is a noticeable effect on spacecraft as high as 75 miles. The average distance from the earth to the moon is 233,000 miles.
27.5 miles. It's above about 98% of the Earth's atmosphere.
230 miles out into space
That sounds like a description of the "jetstream"

The end of the atmosphere is about 63 miles above the surface of earth
High Atmosphere was created in 1965.

The stratosphere is one of many layers in the atmosphere on Earth. It begins at 10 kilometers (8 to14.5 miles) and ends at 50 kilometers high (about 30 miles).
Most require the lower bearings in the engine be replaced at 500,000 miles but other than that assuming routine maintenance many go well beyond a million miles.
Uneven heating in the atmosphere causes pressure differences and when air is in high pressure, it moves toward an area of lower pressure, and that is how wind starts.
The exosphere goes from about 400 miles (640 km) high to about 800 miles (1,280 km).
