Tropical Cyclone Introduction
A tropical cyclone is a warm-core, low pressure system without any "front" attached, that develops over the tropical or subtropical waters, and has an organized circulation. Depending upon location, tropical cyclones have different names around the world. In the:
Atlantic/Eastern Pacific Oceans - hurricanes
Western Pacific - typhoons
Indian Ocean - cyclones
Regardless of what they are called, there are several favorable environmental conditions that must be in place before a tropical cyclone can form. They are:
Warm ocean waters (at least 80°F / 27°C) throughout a depth of about 150 ft. (46 m).
An atmosphere which cools fast enough with height such that it is potentially unstable to moist convection.
Relatively moist air near the mid-level of the troposphere (16,000 ft. / 4,900 m).
Generally a minimum distance of at least 300 miles (480 km) from the equator.
A pre-existing near-surface disturbance.
Low values (less than about 23 mph / 37 kph) of vertical wind shear between the surface and the upper troposphere. Vertical wind shear is the change in wind speed with height.

"Atlantic/Eastern Pacific Oceans - hurricanes

Wrong!
Typhoons are in the South China Sea, the northwest Pacific. Tropical cyclones are in the Indian Ocean and the south Pacific ocean. Tropical cyclones are usually called "cyclones" for convenience in those countries that get them.
I work in one of Australia's three Tropical Cyclone Warning Centres. We currently have TC "Melanie" off the north coast of WA and a low in the Coral Sea which is looking interesting.

A tropical cyclone has a heat-air middle, and develops over heat waters (80F or greater usually). An extratropical device has a cool-air middle and could improve over cooler waters- as low at 65F each so often. As for what occurs, i could assume that this could advise that the tropical cyclone has moved over cooler water (which contain a typhoon entering into the Arctic Ocean) and to that end, the midsection had cooled because of the ability of the device coming from chilly water as a replace of warmth water.

OK this only happens in the summer time. What and how they do is when warm and cold air meet it forms a low pressure. But when the low pressure has 30 or 35 MPH winds it becomes a tropical depression and sometimes these kind of storms form way far out in the Atlantic. When a Tropical storm forms it has to have winds up to 40 or 45 MPH for a tropical storm to form. But when a hurricane forms the winds have to be up to74 MPH for a hurricane to form either in the Atlantic the Gulf of Mexico or in the Pacific Ocean. everything has to be right for it to form.

Tropical cyclones begin with intense convection of water over warm seas.As the storm begins to spin,set in motion by the coriolis force,the wind strengthens.
A warm sea surface(atleast 26.5 degree celcius),moist layers to a considerable height in the atmosphere,steep lapse rate and a pre-existing disturbance are some of the essential conditions for the formation of such storms.

Heated air rises while cool air lowers. They passed each other and building up velocity. Over time, you got some nasty tropical cyclone..
