how will a wind blowing to the south in the northern hemisphere be affected by the coriolis effect
Westerlies If the Earth were a non-rotating planet, solar heating would cause winds across the mid-latitudes to blow in a poleward direction, away from the subtropical ridge. However, the Coriolis effect caused by the rotation of Earth causes winds to steer to the right of what would otherwise be expected across the Northern Hemisphere, and left of what would be expected in the Southern Hemisphere.[3] This is why winds across the Northern Hemisphere tend to blow from the southwest, but they tend to be from the northwest in the Southern Hemisphere.[4] When pressures are lower over the poles, the strength of the westerlies increases, which has the effect of warming the mid-latitudes. This occurs when the Arctic oscillation is positive, and during winter low pressure near the poles is stronger than it would be during the summer. When it is negative and pressures are higher over the poles, the flow is more meridional, blowing from the direction of the pole towards the equator, which brings cold air into the mid-latitudes.[5]
Tropical cyclone windspeed climatology The strongest winds in a northern hemisphere tropical cyclone is located in the eyewall and the right front quadrant of the tropical cyclone. Severe damage is usually the result when the eyewall of a hurricane, typhoon or cyclone passes over land. The right front quadrant is also an area of a tropical cyclone were the winds are strongest. The reason that the winds are at the front right side of a storm in the northern hemisphere (and the front left hand side in the Southern Hemisphere) is because of the motion of a tropical cyclones motion contributing to its rotation. A 100 mph hurricane while stationary, might have winds of 100 mph on its right side in the northern hemisphere while the rest of the storm might have winds at 70 mph. The location of the right ( or left in the Southern Hemisphere) front quadrant also depends on the storm track. For example, in the northern hemisphere, if the storm was moving west, then the right side is to the north, if it moving north, then the strongest winds will be to the east of the center. [5]
