The low pressure trough connects with the western low pressure area with an axis at about 23-25 degrees north latitude. Around the night of May 29 and May 30, this low pressure trough was weakly compressed by the continental high pressure in the North and gradually moved down to the North region; then from May 31, this low pressure trough is weak and fades away.
From June 2, the western low pressure area tends to gradually expand to the east. The south-westerly winds are moderate to strong.
At high altitude, the wind convergence area above 1500 meters is weak in the Northern mountainous area. From May 29, the subtropical high pressure tends to gradually encroach to the West and cause a convergence of winds above 3000m in the Northern region on May 30.
