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

Research Meteorologist (post-doctoral), under Dr. Jacob Bjerknes, Professor Emeritus of Meteorology, UCLA, and world-renowned author and founder of modern meteorology.  

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

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

Published in a major NORPAX compendium, alongside 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 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.  Published Doctoral Dissertation: "Some Meteorological Aspects of the Seasonal Distribution of Precipitation in the Western United States and Baja California."  Written and published under Dr. Bjerknes. 

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. .Eastern slopes of major mountain ranges receive more early-season precipitation; western slopes, more late-season precipitation.

Significant applications to seasonal assessments of precipitation, and to quantitative precipitation forecasting.

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

In January 1969, satellite charts showed giant plumes of cloudiness streaming north from the equatorial zone, directly into Southern California, producing up to 55 inches of rain in 11 days in mountains northeast of Los Angeles.   

Major applications to the forecasting of intense western U.S. storms, and to the determination of 100-year rainfall, capital storms, standard project storms for flood control, and probable maximum precipitation for the safety of dams.

Graduate Student of  Dr. J. Bjerknes, Professor of Meteorology, UCLA. 

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

West Coast precipitation over the past 150 years shows periods of highly anomalous  monthly and seasonal precipitation, lasting 15 to 30 years.  This turned out to be predecessor discovery of 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 Meteorology Major.  Climatology, Physics, Mathematics, and Geography Minors.

Pyke, Charles B.  "On the Role of Air-Sea Interaction in the Development of Cyclones."  Written under Dr. Joanne Simpson (Dr. Joanne Malkus at the time), Professor of Meteorology, UCLA.  Paper won national MacElwane Award for pioneering original 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 and increases the storm's circulation.  Example:  "Nor'easters" off the eastern United States.  

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

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