QUANTUM FITOMETEOROLOGY
Abstract
Factor analysis of three-hour dynamics from 01.01.2012 to 31.10.2018 of four meteorological parameters: atmospheric pressure; air temperature; relative humidity; dew point temperature was carried out by the method of identification (weather station Yoshkar-Ola, Russia, WMO_ID=27485). Power selection when accounting periods of the growing season of birch from 01.05 till 30.09 made 8558 instead 19713 lines in comparison with the continuous series, while there have been significant changes in the laws. The coefficient of correlative variation became equal to 0.3887, which is less in comparison with the full range of data 0.4583. The rating of factors stood on influencing variables equally with a full range: on the first place there is an air temperature, and on the second ? dew point temperature. But according to the dependent indicators, due to the introduction of the periodicity of the birch vegetation, the dew point temperature comes first. The dynamics of air temperature occurs with a constant daily period, and the dynamics of relative humidity is approaching the daily cycle. The frequency characteristics of the air temperature and relative humidity do not depend on the type of series. The values of the oscillation amplitude depend on it.
