Why do you use D to describe the tropical storm that landed in the typhoon in the weather forecast?

Answer the landlord: The symbol was used before the typhoon landed, and I think the landlord also knows that it is a "red circle up and down the tail";

After the typhoon landed, the friction with the ground and the weakening of energy supplement began to weaken;

Once a typhoon weakens, it is not called a typhoon, so it can't be represented by the red circle up and down the tail.

The level of typhoon weakening is typhoon-strong tropical storm-tropical storm-tropical depression.

The typhoon weakened and the tropical storm weakened into a low-pressure system after landing, so the symbol was represented by "D".
