This paper considers the impact of fog, freezing conditions, air quality and heat waves on the San Joaquin. Discussion Air quality: The San Joaquin Valley frequently experiences some of the
worst air pollution in the country, thanks to high concentrations of particulate matter in the region (Herner et al, 2006). In the winter, high pressure systems often remain over the
San Joaquin Valley for extended periods of time; days or even weeks (Herner et al, 2006). These systems usually have higher temperatures at higher altitudes and low winds and low
air pressure between the San Joaquin and neighboring airsheds (Herner et al, 2006). This combination of atmospheric conditions creates an inversion that in effect "caps" the valley so that pollutants
cannot mix above a certain altitude (Herner et al, 2006). Typically during a diurnal cycle, a strong second inversion forms at night, close to the ground; the ground, contrary
to what might be expected, cools the atmosphere by radiating energy from below (Herner et al, 2006). The surface layer created in this way is shallow and traps primary pollutants
that appear at night, which leads to heavy concentrations of the substances in the evening (Herner et al, 2006). There are secondary pollutants produced in this shallow layer, but they
usually disappear at night because the rate at which they are removed is greater than the rate at which they can be produced in this layer (Herner et al, 2006).
The next day, however, the cycle becomes more complex. It begins when the ground heats up from solar radiation; this heating breaks down the stagnant layer that formed the
night before and allows pollutants to mix up to the elevation of the temperature inversion (Herner et al, 2006). At ground level, the concentration of primary pollutants decreases during the
