convections
Warm air rising
Convections is the plural of convection, the transfer of heat through fluid movement—warm material rises while cooler material sinks to replace it.
The word appears most often in scientific contexts discussing atmospheric or oceanic circulation patterns: The convections in the upper atmosphere drive weather systems.
A convection oven uses fans to circulate hot air for more even cooking.
