Office Hours


         Jian-Hua (Joshua) Qian is an Associate Professor in Atmospheric and Climate Science in the Department of Environmental, Earth and Atmospheric Sciences at University of Massachusetts Lowell, USA. He received his Ph.D. in Atmospheric Science from North Carolina State University in 1996. He was a postdoctoral scientist in the Climate and Global Dynamics Division of NCAR from 1996 to 1998, and a research staff in the Mesoscale Atmospheric Processes Branch of the NASA Goddard Space Fleight Center. He was an Associate Research Scientist (2000-2007) and Research Scientist (2007-2011) at the International Research Institute for Climate and Society (IRI) at Columbia University in the City of New York.

       He is now an Adjunct Research Scientist at the IRI. He has experience in regional weather and climate modeling over North and South America, and East, South and Southeast Asia. He also has experience in mesoscale precipitation processes, land-atmosphere interaction, global nonhydrostatic atmospheric model development and theory of atmospheric nonhydrostatic normal modes.

Research Interests

         Qian is interested in understanding atmospheric physics and dynamics and using weather and climate information and forecasts towards good stewardship of the Earth's natural resources, including agriculture, ecosystem, water resource management, environmental protection, and sustainable development.


          Qian works on the development, testing and validation of regional scale forecast systems, and downscaling methodologies to address nesting strategies, physical parameterizations, initialization, forecast validation and analysis, and the dynamics of regional scale climate variability. Qian is also interested in nonhydrostatic atmospheric dynamics and tropical meteorology.
Research areas include: 

    1.    Seasonal climate forecast " (audio video)
    2. Climate downscaling and prediction using global and regional climate models such as
    3. Climate analysis using the IRI Data Library and
      Climate Predictability Tool (CPT)
    4. Atmospheric dynamics and physics
    5. Land-ocean-atmosphere interaction
    6. Interdisciplinary studies on climate risk management
