This picture show the patterns of "Mistral Winds."The High Pressure Cell is anti-cyclonic as opposed to the cylonic Low Pressure Cell. Both working together to push the winds southeast. |
Since air always moves from high pressure to low
pressure there is another interesting phenomenon that leads to the climate at
the Calenques. This is the diurnal
flow.
In the daytime breezes flow inland and at night
breezes flow out to sea.
This park is
right next to the sea and at the base of the mountains causing heavy
changes in pressure and temperature throughout the day. The land heats faster and cools faster than
the sea so this creates a daily pattern of changes in direction of breezes. With this change in heat the air will flow from the colder sea to
warmer land in the day rising when it heats and falling as it cools and vice
versa at night. The motion of air coming
off the Mediterranean is what gives Provence more accumulated annual rainfall
per year than many inland regions of France.
Water heats slower and retains its heat longer because
it is translucent and constantly mixing colder water
with warmer water while land is opaque and has no
mixing as show in this picture.
