What are the conditions necessary for a tropical storm to become a hurricane?

  • For the sustained wind speed to reach 74 mph. If the sustained wind speed is between 39 and 73 mph, it's a tropical storm.

     Quicker wind speed & more torrential rain I guess zxyvbf

    According to the latest Simpson scale, a tropical storm - usually with winds of up to 40 mph but under 74 mph - has to be upgraded to a hurricane when the winds - the sustained winds (not gusts) - reach 74 mph. A wind sustained to 74 mph or a bit more is called a Category 1 Hurricane. There are 5 categories of hurricane strength. 

    To get that to this more intensified strength, there needs to be more warm water at the surface of the tropical storm to allow for much more buoyancy and convective energy at the surface, since warm water holds more moisture that can be shot up adiabatically to the sky and make the planetary boundary layer much more tempestuous.

    A tropical depression to form over a large body of water. Then the in-rushing air from outside will start a vortex and rising warm, moist air forming clouds to rise and cool creating a pressure difference for more warm, most air to try and rise to fill. The stronger it gets, the more likely it will grow into a hurricane.

    Weak vertical wind shear ... sufficiently warm ocean water temperatures to a depth of 50 meters (~165') ... and moist mid-levels of the troposphere are the conditions necessary for a tropical storm to become a hurricane.  Just b/c these conditions exist doesn't guarantee a tropical storm will intensify to hurricane strength.

    Warm water and strong winds

    Warm seas. The only difference between a tropical storm and a hurricane is energy, energy measured in wind speed. Such storms get their energy from warm seas, seas that let off a lot of heat energy, which gets converted into wind energy in the atmosphere. The reason storms lose energy as they move away from the equator, north in the norther hemisphere and south in the southern hemisphere, is sea temperatures that feed them their heat energy get cooler as storms move farther and farther away from the equator, where they're warmest. The storms would die out anyway, though, because the storms themselves, by siphoning that heat energy off of the seas, cool the seas beneath.

    wind speed has to reach 74 mph to be categorized as a hurricane
