Abstract:
Fog and low stratus clouds (FLS) form as a result of complex interactions of multiple factors in<br/>
the atmosphere and at the land surface and impact both the anthropogenic and natural environments. Here, we<br/>
analyze the role of synoptic conditions and aerosol loading on FLS occurrence and persistence in the Po valley<br/>
in northern Italy. By applying k‐means clustering to reanalysis data, we find that FLS formation in the Po valley<br/>
is either based on radiative processes or moisture advection from the Mediterranean sea. Satellite‐based data on<br/>
FLS persistence shows longer persistence of radiatively formed FLS events, likely due to air mass stagnation<br/>
and a temperature inversion. Ground‐based aerosol optical depth observations further reveal that FLS event<br/>
duration is significantly higher under high aerosol loading. The results underline the combined effect of<br/>
topography, moisture advection and aerosol loading on the FLS life cycle in the Po valley.
