East Asia/Typhoon Rule

There is a rule, well explained by Joe Renken, that states a weather phenomenon in East Asia will be reciprocated in the United States 6-10 days later. This means that if there is a storm system in Japan on a certain day, we can expect a storm in the US 6-10 days after that. The same goes for high pressure and warm weather.

Example: A storm system strikes Japan on December 5th.
Result: A storm system can be expected in the United States sometime between December 11-15.

Example: High pressure and warm weather dominate East Asia from March 3rd to 10th.
Result: Warm weather can be expected in the United States sometime between March 9-20.
