Recent Intensified Winter Coldness in the Mid-High Latitudes of Eurasia and Its Relationship with Daily Extreme Low Temperature Variability

Figure 5

Changing zonal mean zonal ((a), unit: Kday⁻¹), meridional ((b), unit: Kday⁻¹), and total ((c), unit: Kday⁻¹) temperature advection anomalies at the 925 hPa level (1979–2013). Values are calculated at each grid point before area averaging and are calculated for 5° latitude bands.
