Why do you see precipitation near the L?
because that is low pressure and that is where air rises, forming clouds
because that is where air is falling and it brings rain with it
because the mid-west is always rainy this time of year
because cold more dense air is sinking forming clouds

Coriolis Effect.
Convection
Global winds curve because of the Earth's rotation. This is called

How are the convection currents in the lava lamp different than convection currents in the atmosphere?
warm air in the atmosphere sinks instead of rises
The earth gets its heat from the sun and the lava lamp gets its heat from the light bulb below.
Convection cells in the atmosphere flow in the same direction instead of opposite
Cold air is less dense instead of being more dense.
