  • I have received a five-year Independent Research Fellowship from the Natural Environment Research Council! My fellowship, "The role of air-sea interactions in sub-seasonal variability", will begin in late March 2015.

  • Our research on improving the simulation of the Madden-Julian oscillation in the Met Office Unified Model has produced two peer-reviewed publications in the Quarterly Journal of the Royal Meteorological Society, covering the roles of convective entrainment and air-sea interactions. These publications are open-access, available to all for free.

  • My father, William Klingaman, and I have co-authored a book on the "Year Without a Summer" in 1816! You can order it from Amazon in the US or the UK!


I am a Senior Research Fellow with the National Centre for Atmospheric Science and the Walker Institute at the University of Reading.

Most of my research focuses on tropical climate variability and change. I am particularly interested in the Madden-Julian oscillation (MJO), a large area of deep tropical convection and heavy rainfall that moves eastward around the equator every 30-60 days. Clear skies, light winds and dry conditions occur before and after each burst of MJO activity. MJO events usually begin in the Indian Ocean, but as they move around the equator they influence monsoon rainfall in India, southeast Asia, Australia and Africa. Predicting these events is therefore crucial for forecasting the weather in those parts of the world. You can see an animation of the rainfall anomalies, derived from TRMM satellite estimates, associated with the composite (average) MJO active/suppressed lifecycle.

I have also worked closely with the Queensland Government to understand the drivers of past rainfall variability in Queensland (northeastern Australia), as well as the likely impacts of climate change on rainfall over the coming decades. Queensland has experienced considerable year-to-year and decade-to-decade changes in its rainfall throughout the past 100 years, so it is critical to understand the causes of these and how they may vary as the world warms.

On this site, you can find out more about my research, learn about the public statements that I have made about my research -- mostly in relation to extreme weather in Australia -- and discover what else I am involved in at the University.

Oh, and if you're interested in my opinions on various climate (and occasionally non-climate) issues, you can follow me on Twitter @nick_klingaman.
