The macroscale winds are the largest of the patterns in wind. It includes westerlies as well as trade winds, hurricanes and tropical storms. It can remain at a time for several weeks. A synoptic scale is an example of a smaller macro scale circulation and that includes the mid latitude cyclones and the anticyclones.
The macro scale of atmospheric circulation includes mid-latitude cyclones, anticyclones, and tropical cyclones.
<u>Explanation</u>:
There are three major scales of atmospheric circulation viz., global-scale atmospheric circulation, macroscale atmospheric circulation, and microscale atmospheric circulation.
The synoptic scale forms a part of the macroscale circulation which consists of mid-latitude cyclones and anticyclones.
The tropical cyclones and hurricanes are a part of the larger macroscale circulation.
The atmospheric circulation is categorized in these three scales on the basis of their strength and expanse.
