Zróżnicowanie przestrzenne elementów meteorologicznych i ich wpływ na rozwój kasztanowca zwyczajnego (Aesculus hippocastanum L.) w warunkach miejskich Poznania

Abstract

We explored differentiation of topoclimatic conditions in the center of Poznañ. Studies were conducted on 21 sites, between March 10 and December 12, 1999. On an hourly basis, four meteorological parameters were automatically measured using battery-operated HOBO data loggers: air temperature, dew point, absolute and relative air humidity. Based on these measurements, humidity deficit was calculated. We found significant differences in air temperature and humidity among studied sites. The main factors affecting observed meteorological differences were substrate parameters and the modifying effect of surface cover in an urban environment on variation in air humidity.
