The atmosphere of the circumjacent seas being colder, more condensed, and thicker, is filled with clouds drawn from the water by the great heat of the summer, and which, driven and agitated by the winds, discharge themselves naturally upon land, where the atmosphere is hotter, more rarefied, lighter, and less resisting than on the sea; and thus this discharge is more or less tardy and plentiful, according as the heat comes early or late, and is more or less intense. It is also in accord with the observations contained in this dissertation to suppose that if the rains commence sooner on the coast of Koromandel than on the coast of Malabar, it is only because the summer is earlier; and that it is earlier may be owing to particular causes which it would not perhaps be difficult to ascertain if the country were properly examined. We know that according to the different situations of lands, in respect of seas or mountains, and in proportion as they are sandy, hilly, or covered with wood, summer is felt more or less early, and with greater or less violence. - [Previous: 21.2](https://indike.org/pramana/in.darkages.travel.bernier~en-constable.21.2) - [Next: 21.4](https://indike.org/pramana/in.darkages.travel.bernier~en-constable.21.4) - [Up: 21](https://indike.org/pramana/in.darkages.travel.bernier~en-constable.21) --- Source: [https://indike.org/pramana/in.darkages.travel.bernier~en-constable.21.3](https://indike.org/pramana/in.darkages.travel.bernier~en-constable.21.3) · Pramāṇa
