My research interests are in meteorology and oceanography, on both weather and climate time scales, through observational data analysis and numerical modelling. These include:

• The Madden-Julian Oscillation (MJO). This is the major source of weather variability in the tropical atmosphere and ocean on week-to-week time scales. In addition to research on basic MJO processes, we now issue a daily operational MJO forecast.
• We have recently taken part in the CINDY/DYNAMO field experiment to investigate the triggering of the MJO, where we deployed a Seaglider in the Indian Ocean.
• Scale interactions in the climate system, including the Cascade project: very high-resolution modelling of the scale interactions between convection and atmospheric dynamics that lie at the heart of understanding tropical weather and climate.
• The West African monsoon, as part of the AMMA project.
• Triggering of volcanic activity by intense rainfall, as part of a project on the current eruption (1995-present) at the Soufrière Hills Volcano, Montserrat.
• South Pacific Convergence Zone (SPCZ)
• Tropical-extratropical interactions in the atmosphere
• Tropical Atlantic variability and teleconnections with the global climate.
• Normal modes of the atmosphere.
• Earth system science, study of the past climate of the Earth.
