| Zusammenfassung |
Temperature sounding of the atmospheric boundary layer (ABL) and lower
troposphere exhibits multilayered temperature inversions specially in high
latitudes during extreme winters. These temperature inversion layers are
originated based on the combined forcing of local- and large-scale synoptic
meteorology. At the local scale, the thermal inversion layer forms near the
surface and plays a central role in controlling the surface radiative
cooling and air pollution dispersion; however, depending upon the large-scale synoptic meteorological forcing, an upper level thermal inversion can
also exist topping the local ABL.
In this article a numerical methodology is reported to determine thermal
inversion layers present in a given temperature profile and deduce some of
their thermodynamic properties.
The algorithm extracts from the temperature profile the most important
temperature variations defining thermal inversion layers. This is
accomplished by a linear interpolation function of variable length that
minimizes an error function. The algorithm functionality is demonstrated on
actual radiosonde profiles to deduce the multilayered temperature inversion
structure with an error fraction set independently. |
