Answer
In Southeast Asia, a tropical cyclone is commonly referred to as a typhoon. Therefore, the answer is F.
Step 3

Answer
The area with sinking, cooler air that is characterized by no rain is referred to as the eye. Thus, the answer is G.
Step 4

Answer
This describes the formative stage where cooler air enters and raises the pressure, which corresponds to D.
Step 5
2.1.5 Pressure drops to below 1 000 hPa and wind speeds increase to approximately 120 km/h in this stage
