Abstract

The routine monitoring of weather and turbulent characteristics in the atmospheric surface layer at the Basic Experimental Observatory of the Institute of Atmospheric Optics SB RAS revealed some particular cases in the behavior of vertical turbulent heat fluxes Q_z at close heights. Atmospheric parameters were monitored with two Meteo-2 ultrasonic weather stations installed at the same tower at heights of 5 and 10 m. There were particular cases that heat fluxes observed simultaneously at heights of 5 and 10 m had different signs, that is, the antiphase effect took place. The cases that the vertical heat flux was negative at a height of 5 m and positive at 10 m (antiphase of Type 1) and that the heat flux was positive at 5 m and negative at 10 m (antiphase of Type 2) were observed. Vertical heat fluxes measured in 2018–2021 are analyzed.
