Heterogeneous processes in the Po Valley radiation fog
Journal of Geophysical Research: Atmospheres, 1988The heterogeneous processes responsible for fog water chemical composition are examined in this paper. SO2/SO4= and NOx/HNO3/NO3− systems have been particularly investigated for their role in the production of acidity within the dispersed liquid phase.

Summer daily circulation in the Po Valley, Italy
Geophysical & Astrophysical Fluid Dynamics, 1981Abstract Surface wind data from a network of stations located in the Po Valley, Italy, have been analysed in order to investigate the features of the local circulation during summer, under synoptic conditions of weak pressure gradients. The up-valley wind appears to be closely coupled with the sea-land breeze in the eastern part of the valley.

Atmospheric-dispersion parameter evaluation in the Po Valley
Il Nuovo Cimento C, 1980Comparison of turbulent-diffusion parametersσ v andσ z, evaluated through different experimental tests carried out in the Po Valley in the range (102÷104) m downwind the source, under neutral and unstable conditions, is presented and discussed. Two kinds of methods of tracer dispersion were adopted.

A climatological study of thunderstorm activity in the Po Valley
Theoretical and Applied Climatology, 1995After a description of the monthly distribution of thunderstorm occurrence in the Po Valley and in the Northern Adriatic region and an identification of the homogeneous areas in terms of the contemporary occurrence of the phenomenon, this study examines the dynamic and thermodynamic characteristics of the atmosphere that are conducive to the ...

The determination of the optimum stack height in the Po valley
Il Nuovo Cimento C, 1979Several experimental studies, carried out in recent years in the Po Valley, regarding typical meteorological conditions and the applications of the most recent dispersion models, enabled us to state the optimal chimney height related to air pollution problems. It appears that a chimney (170÷180) meters high is sufficient to ensure sufficient dispersion

On the origin of aerosol in an agricultural area of the Po Valley
Journal of Aerosol Science, 1977Abstract Measurements of mass concentration of particulate ammonium and sulphate in the atmosphere were carried out, in order to study the importance of soil surface on aerosol formation. The measurements were performed in an observatory along the eastern side of the Po Valley, surrounded by a large agricultural area in which a great use is made of ...
