A POSSIBLE MECHANISM FOR THE EFFECTS OF THE SOUTHERN HEMISPHERE ON THE SEASONAL TRANSITION OVER THE NORTHERN HEMISPHERE IN EARLY SUMMER

The trigger role of the Southern Hemisphere is stressed. In the light of this, the similarities and differences between the Mei-yu in China and the southwest monsoon in India are discussed.
