This creates a stable layer of warm air above the cooler surface air.<\/li>\n<li>Turbulence induced inversion: This type involves a stable air layer situated above a turbulent layer, where the lower layer experiences convection.<\/li>\n<\/ol>\n<div class=\"embed-container\"><iframe loading=\"lazy\" title=\"Radiation Inversions\" width=\"1170\" height=\"658\" src=\"https:\/\/www.youtube.com\/embed\/TDhoaeZQ_Lo?feature=oembed\" frameborder=\"0\" allow=\"accelerometer;
