"The huge Indian Ocean constitutes a maritime space less cohesive than the Mediterranean; yet, the monsoons provide a degree of geographic unity. In winter months, approximately November through March, high pressure zones over the Asian landmass and low pressures over the ocean produce prevailing winds blowing in a southwesterly direction from India and from China. In the summer months, approximately April to September, the pressure zones and wind directions reverse. The optimal sailing periods during the monsoons were relatively short and storms were often a problem, so mariners learned to catch the winds at certain times, depending on their points of embarkation and destination. Some historians argue that the monsoons determined certain historical patterns, and there is a general consensus that the monsoons made cross-cultural experiences highly likely, such as those between Arabia and East Africa and between China and island Southeast Asia. The monsoons also heightened opportunities for sailing long distances more quickly than would otherwise have been possible and thereby made the huge region seem a bit smaller.”
