Probability of occurrence of blowing snow

摘要: Blowing snow (snow transport) affects cover distribution and snowmelt runoff patterns in cold, wind-swept regions. This paper uses a statistical method to examine the occurrence of blowing meteorological conditions recorded for 16 stations on prairies western Canada over six winters. The results show that probability is highly related wind speed, air temperature age. For same age, increases with increasing speed. respect speed approximates cumulative normal distribution, depending mean variance speed: location scale parameters distribution. It was found these two essentially indicate resistance sensitivity transport. Analysis distributions different classes age reveals generally temperature. leads development model which first estimates using then function. Comparison hours fluxes transport sublimation estimated those determined observations shows good agreement. this study can be used estimate frequency events standard data, determine fluxes, effect processes.
