Temperature inversion characteristics in relation to synoptic circulation above Athens, Greece.

Area of Science:

• Meteorology and atmospheric science.
• Boundary layer meteorology.
• Climatology of atmospheric phenomena.

Background:

• Atmospheric inversions significantly impact air quality and weather patterns.
• Understanding lower boundary layer inversions is crucial for urban atmospheric studies.
• Athens, Greece, experiences unique meteorological conditions influenced by its geography.

Purpose of the Study:

• To investigate the characteristic properties of lower atmospheric boundary layer inversions over Athens.
• To analyze the seasonal variability of inversion parameters.
• To explore the relationship between synoptic circulation patterns and inversion characteristics.

Main Methods:

• Utilized 35-year radiosonde measurements.
• Analyzed data on temperature, humidity, and atmospheric pressure.
• Correlated inversion parameters with synoptic weather conditions.

Main Results:

• Inversion parameters exhibit significant seasonal variations.
• Inversions associated with weak anticyclonic conditions are frequent in winter and summer.
• Weak low-pressure systems are more likely to produce inversions during spring.
• Identified expected associations between synoptic patterns and inversion parameters.

Conclusions:

• Lower boundary layer inversions over Athens display distinct seasonal patterns.
• Synoptic weather systems play a predictable role in the formation of these inversions.
• The findings contribute to a better understanding of Athens' atmospheric boundary layer dynamics.
