Weather Regimes To provide a synoptic-planetary perspective and compare atmospheric circulation patterns during the two MWDS winters, we used the weather regime catalog of Guirguis et al. (2022), which evaluates the daily joint phase relationships between four regionally important modes of atmospheric variability (Guirguis et al., 2020). We extended this product to include the winter of 2021–2022. We focus on the days of the MWDS period (30 December–18 February) shared between the 2 years.
