Notes on weather analysis and forecasts
"Wind is air molecules seeking equilibrium."
Air travels from high pressure zones to low pressure zones, which is caused by uneven warming of the Earth's surface by the sun.
During the day the sun warms up the land. There, the warm air rises, creating a low pressure on the surface and clouds in higher altitudes. The colder air from the sea is pulled towards the land to balance the low pressure zone, creating a sea breeze.
Coriolis Effect
A deflection pattern caused by the difference in Earth's rotation speed: it rotates faster around the equator than around the poles. Fluids, air currents and other objects that aren't firmly attached to the ground have the tendency to turn right on the northern hemisphere and left on the southern hemisphere. This causes many of the large scale weather patterns, such as the rotation direction of storms.
Creating an Affected Forecast
- Begin from an understanding of the Earth atmosphere system
- Interpret the data
- Analyze the way it affects us
- Derive a plan with contingencies
- Pilot
