However, it truly is accurate that winter nights may be cold, as it may possibly fall for the freezing issue and in some cases below, particularly in higher-elevation parts. The frequency of subfreezing Wintertime nights from the Sahara is strongly motivated via the North Atlantic Oscillation (NAO), with hotter winter temperatures in the course of negative NAO events and cooler winters with far more frosts in the event the NAO is beneficial.[24] It's because the weaker clockwise movement across the jap aspect with the subtropical anticyclone during adverse NAO winters, Even though too dry to supply greater than negligible precipitation, does reduce the circulation of dry, cold air from increased latitudes of Eurasia into the Sahara considerably.[twenty five]
