| Zusammenfassung |
| The potential of instability indices in assessing atmospheric instability is
examined for the areas of Attica, Thessaly and Central Aegean and Crete,
Greece. Generally, many indices have been developed to estimate the
troposphere's stability for forecasting purposes. At this study several
instability indices, commonly used in Meteorology, are computed based on
radiosonde data. Firstly, the indices are computed for several months based
on the 00:00 and 12:00 UTC radiosonde data during the period 1981–2003.
Statistical methods were used to compare and test the effectiveness of these
indices in the described area using meteorological data from seventeen
meteorological stations of Greece. Thus, the potential of monitoring the
atmospheric instability conditions is examined. The next stage of this study
is an effort to test the thresholds of the existing indices in order to
improve the results of these indices. It seems that this effort can make a
good simulation to the assessment of instability, contributing to local
level weather forecasting. |
