Navigators must allow for deviation to right when flying in northern hemisphere -- and to left in southern hemisphere.
The rotation of the earth creates special problems on flights to and from the moon.
created by high to low pressure have a right hand deflection that creates cyclones, hurricanes and typhoons, in the northern hemisphere.
the rotation of earth results in wider distribution of rain over the earth. If no frequent spin, there would be a steady flow of cool air from pole to equator. The cool air would be near the surface; as it warmed, the air would gradually rise and flow back toward the the pole, dropping its water content as it again cooled. This would tend to produce constant rain near the equator and deserts in the northern and southern parts of the world. The rotation of the earth helps break up this north-south cycle by introducing an east (or west) deflection.
