Flying in hot temperatrue is similar to be faced in high altitude. Hotter air is less dense, which means there is less air beneath the wings for lifting the aircraft and less air to flow through the jet engines. This affects the output of the engines as well as aerodynamic capabilities, incresing the required runway distance and reducing climb performance. Therefore the amount of passengers and cargo a plan can carry are often restricted when temperatures are very high.

The 4th Typhoon TALAS is heading toward near Hanoi with a speed of 42km/h and weakening. Because once Typhoon lands on the continent, they can't get energy from the ocean. Here's the interesting one to read about relationship between El nino and Typhoon.
By using 25 years meteorological data of KMA and JMA, Annual mean number of typhoon's occurences in El Nino event year is 23.9 and that in La Nina event year is 24.9. The number of Typhoon's occurrence decreases in El Nino year. Mean central minimum pressure and mean maximum wind speed in El Nino year are 959.3hPa and 35.8m/s, and those in La Nina year are 965.5hPa and 337 m/s respectively. Typhoon is stronger in El Nino year than La Nina year.
This results is closely connected with sea area of typhoon's occurrence. Typhoon in El Nino year are more likely to occur in east of 150E and south of 10N, but those in La Nina year are more likely to occur in 120-150E and north of 20N. Typhoon which occur in east of 150E and south of 10N can be stronger because the typhoons move in broad sea area of hight sea surface temperature in western North Pacific.
KMA announced lately that this year has neither an El Nino nor its opposite, a La Nina. It is neutral year.
How a hurricane differs from a typhoon or cyclone? Mostly where they are and when they hit.
They are all the same, officially tropical cyclones. But we just use distinctive terms for a storm in different parts of the world. Hurrican is used in the Atlantic, Caribbean Sea, central and northeast Pacific. They are typhoons in the northwest Pacific. In the Bay of Bengal and the Arabia Sea, they are called cyclones. Tropical cyclonce is used in the southwest India Ocean.
That's Korea for you.
