A classroom/laboratory activity to learn about radiation, heat transport, convection, and energy/mass conservation by interpreting and mapping the Hadley Circulation.
Students will analyze and map real data through the NASA MERRA reanalysis model to understand the actual impact of the Hadley Cell on the Earth’s climate system (e.g., geographical distribution of deserts, global precipitation patterns, trade winds). Students will visualize 30-year-average data on winds and their vertical velocity to understand the Hadley circulation and its influence of regional climates.
Use this tool to help your students find answers to:
- How does the Hadley cell transport heat in the atmosphere?
- What might be the potential impacts of Hadley Cell expansion on the Earth’s climate, global precipitation patterns, and the geographical distribution of deserts?
