Why are typhoons in the Pacific and hurricanes in the Atlantic? Aren't they basically the same type of storm?

They are the same, I do not know why they have different names due to the region. I guess it’s just like color and colour.

Typhoons are said to be stronger in intensity as compared to hurricanes, because better conditions for the development of a storm are created in the warm waters of the Pacific Ocean. Due to the unlimited amount of warm water, the conditions are favorable for high frequency typhoons. Although the intensity of wind is stronger in a typhoon, they cause less damage as compared to hurricanes, due to their location. Hence, hurricane pictures are always scarier. Read on to know how do hurricanes form and how they are measured using the Saffir Simpson scale.

There are some reports, which say that the wind in a hurricane can blow both clockwise as well as anti-clockwise. On the other hand in a typhoon the wind blows only anti-clockwise.

The frequency of typhoons is approximately 25 to 30 in a year and that of hurricanes is 10 to 15 per year. Both typhoons and hurricanes are given names. These names help in the categorization of these cyclones. Hurricanes are given human names every year, like hurricane Katrina, etc, whereas typhoons around China and Japan are given names of living objects like flowers, etc.

Wiki

Same thing, and they’re called cyclones in the Indian Ocean.

“The terms “hurricane” and “typhoon” are regionally specific names for a strong “tropical cyclone”. A tropical cyclone is the generic term for a non-frontal synoptic scale low-pressure system over tropical or sub-tropical waters with organized convection (i.e. thunderstorm activity) and definite cyclonic surface wind circulation (Holland 1993).”
