Like other sciences, the Science of Climatology also was well developed in ancient India. It is regrettable that now a day we do not pay proper attention to our ancient Indian sciences. This is because some how we have formed a notion that ancient Indian sciences have lost all their utility in the face of the modern science which have developed so much to their present position. But this concept of ours will prove false if we try to realize the real merits of the ancient Indian sciences.
The main difference between the modern sciences and ancient Indian sciences is that in modern sciences, the deeper we go the more we have to depend upon costly machines and other equipments. So here in the machines seem to have more importance than the scientist himself. But in ancient Indian sciences no costly machines or equipments are needed and the scientist is able o carry on his work, anywhere, without costly machines and well equipped laboratories. From the study of different ancient Indian sciences we gather that ancient Indian scientists, instead of depending upon man made machines and equipments, have always tried to adopt and utilize natural object easily available around us. Thus the earth and the atmosphere had been their laboratory wherein the animals, plants and other natural objects had to serve the purpose of instruments and equipments.
