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

Research Meteorologist (post-doctoral), 1972-1976, under Dr. Jacob Bjerknes, Professor Emeritus of Meteorology, UCLA, and world-renowned author and founder of modern meteorology.

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. 

Comprehensive  Research Publication, published in a major NORPAX compendium, on the reasons that regions from Southern and Central California, and often northern Mexico, eastward to southern Mississippi, Alabama, and Georgia, plus northern Florida, tend to experience much above normal precipitation from January through March and into April during El Niño years.  Many larger river basins frequently flood.

Major applications to long-range weather forecasting, including  seasonal and multi-seasonal weather outlooks, and to water resources and flood control over large areas of the United States. 

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 under Dr. Bjerknes, 1968-1972. 

The month of maximum precipitation in the far western United States progresses southward from November in northwestern Washington to February in Southern California, but jumps back to December in Baja California.  The eastern slopes of major mountain ranges, such as the Sierra Nevada, experience more early-season precipitation than the western slopes.  The western slopes experience more late-season precipitation, often with lower snow levels. 

Significant applications to the understanding of seasonal variations in precipitation west and east of major mountain ranges, to the types and intensities of storms experienced in the western United States, and to quantitative precipitation forecasting in different seasons in various portions of the western U.S.

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

Analysis of major flood-producing January 1969 storms in Southern California, when satellite charts showed giant plumes of cloudiness streaming northward from the equator directly into Southern California, as cold air from the Gulf of Alaska streamed southeastward behind these plumes, greatly intensifying the rainfall in Southern California (up to 55 inches in 11 days along the southern slopes of the San Gabriel Mountains, northeast of Los Angeles). 

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

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

Pyke, Charles B., 1965.  Master's Thesis on precipitation patterns of California: 

Research into geographic sizes of West Coast storms and the distances from the centers of these storms that areas will necessarily be dry . . . plus . . . An analysis of the past century and a half of West Coast precipitation also shows periods of above and below normal precipitation, for the year as a whole, and for individual months and seasons, lasting 15 to 30 years.  This turned out to be predecessor research on climatic variations that were later found to be  components of the  Pacific Decadal Oscillation. 

Significant applications to storm forecasting and to quasi-decadal and multi-decadal variations in Pacific storm tracks and long-term rainfall and snowfall conditions throughout the western United States, including short-term climate changes.  

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 centered a few hundred miles off the coast of a continent during late fall, winter, and early spring, frequently intensify rapidly, as cold air pours out from the continent over warmer ocean water, and thermal energy becomes converted into kinetic energy, increasing the storm's circulation and dynamics, and hence its winds and precipitation. 

This award-winning study was published in the Bulletin of the American Meteorological Society, January 1964, and featured as their lead paper, with a full-page illustration on the front cover of that issue, depicting the wind and waves of a major storm at sea -- demonstrating the air-sea interaction discussed in this paper. 

Major application to the understanding of the rapid development of oceanic storms when fed by cold air pouring out from land masses, and to the forecasting of intense oceanic storms, including "perfect storm" scenarios.
