藤原效應
The same near-equatorial trough that developed Rita also developed Typhoon Tess. Tess, having developed on July 7 near the Marshall Islands, tracked westward, reaching typhoon status on July 12. Over the next two days, as Tess turned to the northwest, it rapidly intensified to a typhoon. Steadily weakening as it continued northwestward, Tess bent back to the west in response to the building of a high pressure cell over Japan. The Fujiwhara effect between Tess and Rita brought Typhoon Tess into Japan on July 23. After dissipating over Sea of Japan, Tess continued northward, and merged with a front south of Vladivostok on July 25.
