The incessant rains that walloped most of east and central Africa for most of the past five months have given way to soothing blue skies. Yet, the effects of the relentless precipitation, caused by

The fires in the Amazon forest show no signs of abating. Lax environmental laws have added fuel to them

Science takes on nature as climatologists try to predict El Ni o patterns in an attempt to warn governments of climatic anomalies

The Colombian government has called upon the European Union to help drought-affected farmers in the country. The government has sought us $2.5 million aid in this regard. The damaging effect of

A weather event which Peruvians once regarded as a boon is now recognised as causing terrible global disasters

Effects similar to those of El Nino have been observed in the Indian and Atlantic Oceans

A warm Pacific current that is the cause of much human misery appears to be brewing again

Despite using satellites and supercomputers, meteorologists are still baffled by the monsoon, unable to say precisely when it will occur and how good -- or bad -- it will be

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.

Observations made during the 1987 El Niño show that in the upper range of sea surface temperatures, the greenhouse effect increases with surface temperature at a rate which exceeds the rate at which radiation is being emitted from the surface. In response to this 'super greenhouse effect', highly reflective cirrus clouds are produced which act like a
thermostat, shielding the ocean from solar radiation. The regulatory effect of these cirrus clouds may limit sea surface temperatures to less than 305 K.
