Question

Middle and upper tropospheric circulation is an important component of the atmosphere's general circulation, as it helps to distribute heat and moisture around the globe. The other options are incorrect: A is incorrect because winds in the thermosphere are not considered part of the atmosphere's general circulation; B is incorrect because upper atmospheric circulation is indeed related to surface weather patterns; D is incorrect because winds in the mesosphere generally flow from the west; and E is incorrect because while stratospheric winds do contribute to the movement of CFCs, they do not flow to the poles exclusively and are not the sole cause of ozone depletion.
