| Zusammenfassung |
| Temperature data recorded in 2002 and 2003 at 10 stations out of
the 70 available in the Romanian automatic weather stations
network are presented and analyzed in terms of the heat transfer
from air to underground. The air temperature at 2 m, the
soil temperatures at 0, 5, 10, 20, 50 and 100 cm below the
surface as well as rain fall and snow cover thickness have been
monitored. The selected locations sample various climate
environments in Romania. Preliminary analytical modelling shows
that soil temperatures track air temperature variations at certain
locations and, consequently, the heat transfer is by conduction,
while at other stations processes such as soil freezing and/or
solar radiation heating play an important part in the heat flux
balance at the air/soil interface. However, the propagation of the
annual thermal signal in the uppermost one meter of soil is mainly
by conduction; the inferred thermal diffusivity for 8 stations
with continuous time series at all depth levels ranges from 3 to
10×10−7 m2 s−1. |
