    Khalid's picture

    Dr. Khalid Malik has obtained his PhD from ESS, York University in 2010 with Prof. Peter Taylor. His PhD topic of research was a study of drought over Central Southwest Asia. He identified the causes of severe drought over the Asian region during 1999-2001 and found tele-connections with different climatic indices. He has developed a seasonal weather model for Pakistan and its neighboring countries including India, Afghanistan, Nepal, Bangladesh, Bhutan and Sri Lanka. The model can also be used for hydrological seasonal weather outlook by simply changing the model input and Regional Correction Factors (RCF) for that particular region. His broad research interests include:
    •    The impact of climate change in the region,
    •    Monsoon dynamics,
    •    The importance of meteorology in the agriculture sector,
    •    Regional weather tele-connection with different climatic indices etc.
