GEOLOGY

Detailed explanation-1: -A tropical storm is called a hurricane when its wind speed exceeds 74 miles per hour.

Detailed explanation-2: -All tropical cyclones: They begin as Tropical Depressions, graduate to Tropical Storms when winds reach 39 miles per hour, and become hurricanes (or typhoons) at 74 mph, at which point they are classified by levels and additional titles.

Detailed explanation-3: -TROPICAL STORM (TS)-a tropical cyclone with maximum wind speed of 62 to 88 kph or 34-47 knots. SEVERE TROPICAL STORM (STS), a tropical cyclone with maximum wind speed of 87 to 117 kph or 48-63 knots. TYPHOON (TY)-a tropical cyclone with maximum wind speed of 118 to 184 kph or 64-99 knots.

Detailed explanation-4: -Terms in this set (23) what is the main difference between a hurricane and a tropical storm? maximum sustained wind speed.

Detailed explanation-5: -The strongest winds are nearly always on the right side of the storm’s forward motion and often in the right-front quadrant relative to the storm’s forward motion. So, direction and speed of the storm’s forward motion will impact the extent of the wind field in each quadrant.
