The correct answer is option B, natural wind patterns
Explanation:
An air mass moves along with the air flow in the upper atmosphere. Whenever a jet stream changes its potion and its intensity of flow, it leads to the movement of air mass. An air mass movement is not affected by the characteristic of its source regions, however the physical characteristic of an air mass(i.e temperature, pressure of air mass etc.) are entirely determined by the physical characteristics of its source region
