Research, and Publications, including Applications to Seasonal Weather Forecasting and the Understanding of Climatic Variations:

Research Meteorologist (post-doctoral), 1972-1975, under Dr. Jacob Bjerknes, Professor Emeritus of Meteorology, UCLA, and world-renowned author and founder of modern meteorology, with major pioneering paper published in 1976.

Pyke, Charles B. 1976:  Effects of Equatorial Pacific Ocean Temperatures on Weather Patterns in the Western and Southern United States.  

Pioneering research paper (post-doctoral) on how El Niño and La Niña affect  weather and precipitation patterns from California to Georgia & Florida. 

Published in a major NORPAX (North Pacific Experiment) compendium, along with articles by Dr. J. Bjerknes, Dr. J. Namias, and other prominent meteorologists and oceanographers.  

Major applications to seasonal and multi-seasonal weather forecasting, and to water resources and flood control. 

Doctoral Student, 1965-1972, of  Dr. J. Bjerknes, Professor Emeritus of Meteorology, UCLA.   Also studied with, and published a joint research paper under, Dr. William D.. Bonner,  Associate Professor of Meteorology, UCLA.

Pyke, Charles B., 1972:  "Some Meteorological Aspects of the Seasonal Distribution of Precipitation in the Western United States and Baja California."  Doctoral Dissertation, written and published under Dr. Bjerknes, 1968-1972. 

The month of maximum precipitation along U.S. west coast progresses southward from November in Washington to February in Southern California, but jumps back to December in Baja California because of warmer ocean in late fall southwest of Baja California. .Eastern slopes of major mountain ranges receive more early-season precipitation (more winds from the east), while western slopes receive more late-season precipitation (more winds from the west).

Significant applications to seasonal variations in precipitation, and to quantitative precipitation forecasting.

Pyke, Charles B.,  W.D. Bonner, and R.J. Hickey, 1969.  Research paper, written and published under Dr. Bonner. 

In January 1969, satellite charts showed giant plumes of cloudiness streaming northward from near the equator directly into Southern California, producing intense rainfall (up to 55 inches in 11 days in the mountains northeast of Los Angeles).   

Major applications to forecasting major western U.S. storms, including probable maximum precipitation (for safety of dams) and 100-year rainfall.

Graduate Student, 1963-1965, of  Dr. J. Bjerknes, Professor of Meteorology, UCLA. 

Pyke, Charles B., 1965.  Master's Thesis on precipitation patterns of California, written and published under Prof. Bjerknes: 

Research into geographic sizes of West Coast storms . . . plus . . . An analysis of the past century and a half of West Coast precipitation shows periods of highly anomalous above and below normal precipitation for various months and seasons -- each period lasting 15 to 30 years.  This research paper turned out to be predecessor discovery of climatic variations later found to be major components of the Pacific Decadal Oscillation. 

Significant applications to storm forecasting and to short-term climate variations in western U.S. precipitation (not associated with Global Warming / Cooling). 

Undergraduate Student, 1956-1957, 1958-1961, and 1962-1963 Meteorology Major.  Physics, Mathematics, Climatology, and Geography Minors.

Pyke, Charles B., 1963:  "On the Role of Air-Sea Interaction in the Development of Cyclones."  Written under Dr. Joanne Malkus  (later  -- and now the late -- Dr. Joanne Simpson), Professor of Meteorology, UCLA.  Paper won national MacElwane Award for original pioneering undergraduate research paper

Oceanic storms off the coast of a continent frequently intensify rapidly when cold air from the continent pours out over warmer ocean water, increasing the storm's circulation and dynamics.  This is frequently seen in the Gulf of Alaska and also off the East Coast of the United States, where major "nor'easters" develop and rapidly intensify.  

This award-winning study was published as the lead paper in the Bulletin of the American Meteorological Society, January 1964, with a full-page front cover illustration of wind and waves.

Major application to the forecasting of intense oceanic storms, including "perfect storm" scenarios.
