In Hadley's cell model warm air rises at the equator and cold air sinks at the poles. Can someone tell me what these 2 questions mean? Surface air flow will be _________. Air flow aloft will be _______. Don't understand those two. Thanks

Thanks for your help.

In Hadley's cell model, warm air rises at the equator and cold air sinks at the poles. This movement of air creates a circulation pattern in the atmosphere. To understand what the questions mean, let's break them down:

1. "Surface air flow will be _________": This question is asking about the direction of the horizontal movement of air at the Earth's surface. Given that warm air rises at the equator and cold air sinks at the poles, the circulation pattern is referred to as the Hadley Cell. In the Hadley Cell, air moves from the equator towards the poles at the surface. So when asked "Surface air flow will be _________," you can fill in the blank with "from the equator towards the poles."

2. "Air flow aloft will be _______": This question is asking about the direction of the vertical movement of air in the upper levels of the atmosphere. In the Hadley Cell, once the warm air rises at the equator, it travels towards the poles in the upper levels of the atmosphere before descending at the subtropics. This vertical movement of air is known as the Hadley Cell's circulation. Therefore, when asked "Air flow aloft will be _______," you can fill in the blank with "from the poles towards the equator."

Overall, the questions are asking about the air movement at different levels of the atmosphere in Hadley's cell model.
