The changing wind patterns are governed by Newton’s second law of motion, which states that the sum of the forces acting on a body equals the product of the mass of that body and the acceleration caused by those forces. The basic relationship between atmospheric pressure and horizontal wind is revealed by disregarding friction and any changes in wind direction and speed to yield the mathematical relationship where u is the zonal wind speed (+ eastward), v the meridional wind speed (+ northward), f = 2ω sin ϕ (Coriolis parameter), ω the angular velocity of Earth’s rotation, ϕ the latitude, ...(100 of 37038 words)
