Warm air from the ____ is distributed to higher and cooler latitudes and ____ air from the poles is distributed to lower, warmer latitudes. Due to the ____ winds are directed to the right in the northern hemisphere. In the Hadley Cell, which is ____ - warm air rises at the equator (0°) and travels in the upper atmosphere to 30°N where it begins to cool and ____. Air then returns from the ____ high pressure area (30°) back to the equator as the ____. In the ____ Cell, which is thermally indirect - at 60°N the cold air from the poles meets warmer air from the tropics creating ____ pressure as the air starts to rise. In the Ferrell cell, air is moved from the tropical HP (30°C) towards the LP at the polar front (60°C) as the ____ wind. In the ____ cell, which is thermally direct - at the North Pole (90°N) cold air is sinking and starts to move along the surface towards 60°N as the ____ wind.
