PPT-Estimation of Surface Pressure & Wind Observation Error

ERA20C Observation Feedback Paul Poli Outline Why we care about observation errors Handling of Gross errors Systematic errors Random errors And lessons learnt from ERA20C Conclusions. Three real forces . (gravity, pressure gradient, and friction) push the air around. Two apparent forces . due to rotation (Coriolis and centrifugal). Large-scale flow is dominated by gravity/pressure and Coriolis … . November 6. th. , 2013. Hurricane Review. Winds rotate counter-clockwise around the . center.

Even though it appears that air has no mass, air consists of atoms and molecules that, in fact, have mass.. Because air has mass, it also has other properties, including density and pressure..
