Dr. F. Martin Ralph is a research meteorologist who has studied mesoscale and synoptic scale weather phenomena and how they are affected by climate variability. A key area of interest is exploring how to best observe the atmosphere, with an emphasis on advancing the physical understanding of extreme precipitation processes as well as related hydrometeorological predictions and climate projections. He is currently Chief of the Water Cycle Branch at NOAA's Earth System Research Laboratory/Physical Sciences Division, and a Research Associate at Scripps Institution of Oceanography.

A major goal is to better understand, monitor, and predict key elements of the global water cycle including water vapor transport, precipitation and runoff. Scientific understanding of atmospheric rivers, which are critical to both the global water cycle and to the distribution of precipitation and flooding in key parts of the world, is a major thrust. Using these results to evaluate and improve short-term precipitation forecasting and to provide reliable regional climate projections of flooding and water supplies in several areas of the world, are desired outcomes.

Dr. Ralph has published over 60 peer-reviewed scientific articles, 23 as the lead author. He has helped lead the establishment of testbeds as a method to accelerate the development and infusion of new science and technology into weather and climate forecasting operations. He has developed new projects, experiments and teams on several subjects, most having to do with observations, physical understanding, and precipitation.
