Background
Jian-Hua (Joshua) Qian 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.
Before came to IRI, he worked in the Mesoscale Atmospheric Processes Branch of the
NASA Goddard Space Fleight Center. 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. See Professional Achievements.
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:
