Peter John Webster is a meteorologist and climate dynamicist relating to the dynamics of large-scale coupled ocean-atmosphere systems of the tropics, notably the Asian monsoon.

After working as a forecaster with the Australian Bureau of Meteorology, Webster attended the Massachusetts Institute of Technology where he was awarded his doctoral degree in 1972.

[1] Research topics range from the low-frequency variability of the climate systems to the prediction of weather hazards in South Asia.

Recent research suggests that monsoon rainfall has actually increased in the last three decades, contrary to the expectation from global climate models.

The Indian Ocean Dipole has emerged as an integral part of variations of the intensity of the South Asian Monsoon.

CFAN was founded in 2006 by Judith Curry and Peter Webster and launched under Georgia Tech's Enterprise Innovation Institute VentureLab program.

The prediction scheme continues to be used in Bangladesh through the Regional Integrated Multi-Hazard Early Warning System (RIMES) based in Bangkok, Thailand.

[6] Webster has continued to call for improved weather forecasts for South Asia, particularly in context of Cyclone Nargis that struck Myanmar[7] and the storm surge from Super Typhoon Haiyan.
