Winds are examples of convections currents
Natural Convection occurs when a warmer less dense fluid is pushed away by a cooler denser fluid. Forced Convection occurs when an outside force pushes a fluid, such as water of air, to make it move and transfer heat. A fan is a perfect example. Im pretty sure air, and heat vents are examples too. An air conditioner is definitely an example.
