Forensic Discovery and Expert Witness Testimony  for litigation and criminal cases.  Management of other expert witnesses and data experts.

Black ice, dew, sun glare, rain, wind, fog, lightning, blowing dust -- contributing to slip and fall, vehicle accidents, structural damage, crop / livestock loss.  PLUS: 

Some unique expert witness specialties of Dr. Pyke and his staff,* almost never found in any discovery performed by other experts, include: 

Slip and fall on black ice in parking lots and other asphalt surfaces:   Experiments and modeling of asphalt surface temperatures, leading to precise opinions.

Slip and fall on wet grass or artificial turf:   Formation and evaporation of rain or dew, by the minute, based on temperature, dew point, wind, sun, and shadows.

Slip and fall on icy or wet sidewalks, driveways, and other surfaces:   Precise calculations of ice or water formation and evaporation to within minutes of the fall.

Personal injury from sudden wind gusts, including dust devils:   Pinpoint calculation and modeling, in space and time, of local wind eddies, including dust devils.

Personal injury, property damage from heavy local downpours or large general storms and floods:   Precise timing and location of intense rain.  Frequency analysis.

Multi-vehicle accidents in pockets of dense fog or severe blowing dust / sand:   Pinpoint detailed accuracy of visibility at the point of each such accident. 

Vehicular accidents in sun glare:   Pinpoint calculation of sun's elevation above horizon and azimuth (E-S-W-N position), plus clouds and haze.  Google Earth photos.

Loss of fruit crop from wind-driven hail, when fruit trees were in full bloom and were stripped:   Calculation of the frequency or rarity of such an event.

Loss of fruit crop from a late freeze that damages fruit buds, blossoms, or growing fruit:   Frequency / return period, or rarity, of such a late-season freeze event.

Fires sparked by power lines downed by wind-blown trees:   Precise timing and location of wind, temperature, and humidity at sites of power lines and spreading fire.

Roof leaks after strong wind gusts tear away tarp or shingles, and rain enters the building:   Precise timing of wind and rain data directly interpolated to site.

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 (warmer ocean in late fall SW of Baja California). .Eastern slopes of major mountain ranges receive more early-season precipitation, while western slopes receive more late-season precipitation (seasonal shift in storm wind direction).

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 north from the equatorial zone, directly into Southern California, producing up to 55 inches of rain in 11 days in mountains NE 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 sizes of West Coast storms, plus West Coast precipitation over the past 150 years shows periods of highly anomalous  monthly and seasonal precipitation, lasting 15 to 30 years.  This thesis 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, 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 and increases the storm's circulation.  This is seen in the Gulf of Alaska and off the eastern United States, where "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.
