Which of the following is a type of general wind?

Explanation:
General wind means the larger-scale wind field that isn’t dominated by surface friction. Winds aloft fit this idea because they occur higher in the atmosphere and reflect the broad, steadier wind pattern over a wide area, which helps set the overall direction the fire might move. In contrast, winds at the surface or near-ground levels are heavily influenced by terrain, obstacles, and friction, making them more variable and localized. Gustfront winds are even more local, arising from the leading edge of a thunderstorm or fire plume and can shift quickly. So winds aloft are the example of a general wind.
