Typhoons start off as tropical thunderstorms with strong winds pull
in moisture from the oceans. A pre-existing disturbance, warm ocean
water, low atmospheric stability, sufficient Coriolis force, moist
mid-atmosphere, and upper atmosphere divergence are all important
factors for typhoon formation.

The moisture is converted into heat through thunderstorms and causes more air to flow to the center of the storm which causes evaporation. The typhoon is a large heat engine, where great amounts of heat are being produced from the heat of condensation. This occurs as water vapor is being evaporated from the ocean surface and condensed into cloud droplets.

All the heat and air flow toward the eye creating the typhoon.
The most common way that a typhoon is caused by is the monsoon trough. This is where the cyclonic spin is developed in the extension of the Inter-Tropical Convergence Zone. The Inter-Tropical Convergence Zone or the ITCZ is a trough of low pressure system created by the convergence of the northeast and southeast trade winds (does not contain the spin to initiate typhoon development).
Another cause is the Tropical Upper Tropospheric Trough. The upper air low is cold in nature as compared to its surrounding environment. A typical low pressure center that forms a typhoon starts at the lower levels and is warm compared to its environment. If the low is remained over warm ocean waters for several days, sometimes it gradually warms and takes on tropical characteristics. By this time, the low reaches down to the surface from the upper atmosphere where the development process transforms.
One more mechanism is from a front which stalls over tropical storms. This has a cyclonic spin along with is. Showers and storms become more numerous when winds become favorable with little wind shear which causes the typhoons to form

In other lands, it can be called tropical cyclones or hurricanes but in the region of the Northwest Pacific, it is called a typhoon. These storms can bring much rain and winds blowing from 38 to 73 miles per hour (62-1017 kilometers per hour). According to NOAA's Hurricane Center, the average eye (still center) can stretch to 30 miles (48 km) to 120 miles (200 km) but these eyes typically shrink when a hurricane intensifies and new eyes may form. At 132 knots (150 mph), a typhoon becomes a super-typhoon. The official seasons for typhoons run from May 15 to November 30 though typhoons are most common from late June through December. Typhoons are sclaed by the Saffir-Simpson scale that goes to from a Category 1-5 where 5 exceed 135 knots (155 miles).
