A 4.80 m long shallow water sediment core, collected from the inner shelf (at 22 m water depth) off Karwar, near Kali river mouth is studied for foraminiferal tracers of palaeomonsoons. The climate history of this core which represents the last 4,500 years approximately revealed the evidences of a significant change in the intensity of the precipitation around 2,000 years BP.

EL Nino refers to the warm current that flows southward along the coasts of Ecuador and Peru, between January and March, which marks the end of the local fishing season when the

In the past decade there has been extensive research into tropical intraseasonal variability, one of the major components of the low frequency variability of the general atmospheric circulation. This paper briefly reviews the state-of-the-art in this research area: the nature of the Madden-Julian Oscillation, its relation to monsoonal and extratropical circulations, and the current theoretical understandings.
