Tropical cyclones usually move in a westward direction.
The wind speed of a severe tropical storm ranges from 39 to 73 mph. They are not formed within 5° latitude of the equator in the Pacific Ocean.
When a typhoon makes landfall, it weakens due to the loss of its primary energy source and the frictional effects of the land surface.
Landforms can affect typhoons by altering their path and intensity, causing them to weaken or change direction, and amplifying storm surges and wind speeds in coastal areas.
Direction of Movement of Tropical Cyclones:
Tropical cyclones typically move from east to west. This movement is influenced by the trade winds in the tropics. The Coriolis effect, caused by the Earth's rotation, imparts a westward component to the storm's motion.
Wind Speed of Severe Tropical Storm:
A severe tropical storm is characterized by wind speeds between 39 and 73 miles per hour (63 to 118 kilometers per hour). At this stage, it is not yet classified as a hurricane or typhoon but represents a significant tropical weather system.
Formation of Tropical Cyclones in the Pacific Ocean:
Tropical cyclones do not typically form in the eastern part of the Pacific Ocean. This is due to cooler sea surface temperatures and less favorable atmospheric conditions compared to the western part of the Pacific.
Impact of Landfall on a Typhoon:
When a typhoon makes landfall, it encounters friction from the land surface, which disrupts the storm's structure. Additionally, the storm loses its primary heat and moisture source from the warm ocean waters, causing it to weaken. Land interaction often leads to the gradual decay and dissipation of the typhoon.
Effect of Landforms on Typhoons:
Landforms can significantly influence the behavior of typhoons. Mountains, for example, can disrupt the structure of a typhoon, leading to changes in wind patterns and precipitation. Coastal geography can also impact storm surge, affecting the severity of flooding during a typhoon's landfall.
