Abstract
The "ramp" is an often observed feature in temperature
fluctuations during unstable atmospheric conditions. It is
characterized by a gradual increase in temperature followed
by a sudden drop to an ambient level. This ramp clearly
distinguishes temperature signals from other turbulence signals
such as velocity. Three different ramp-type atmospheric
temperature fluctuations and their derivatives are constructed
and statistically examined for the parameters skewness and
coefficient of excess., These statistical values are compared
with values obtained from actual signals. The "complex ramp
signal" was found to represent these quite well. Skewness and
coefficient of excess for this signal could be altered almost
independently of each other. The complex ramp is constructed
by inscribing nearly symmetrical consecutive triangles within
two envelope rays of constant but different slopes such that
the two envelope rays approximate a ramp function.
