Write a short note on the western cyclonic disturbances.

The western cyclonic disturbances are weather phenomena of the winter months brought in by the westerly flow from the Mediterranean region. They usually influence the weather of the north and north-western regions of India. Tropical cyclones occur during the monsoon as well as in October-November, and are part of the easterly low. These disturbances affect the coastal regions of the country. They sometimes cause disasters on Orissa and Andhra Pradesh coasts.
