Figure 7. State-of-the-art numerical simulation of a polar low developing over the Norwegian Sea on March 26, 2013. This polar low was targeted by air-borne observations and the numerical simulation shows good agreement with observations (for details, see Sergeev, Renfrew, Spengler, & Dorling, 2017). Shading indicates low-level temperature (units: K), arrows represent low-level wind-speed and direction (see reference vector), and the 3D structure shows total cloud and frozen water.
