Another month in which the monthly MSLPMSLP Mean sea level pressure is the pressure at sea level, or, when measured at a given elevation on land, the station pressure reduced to sea level assuming an isothermal layer at the station temperature. anomaly chart hides what really happened. The first twelve days of the month were dominated by cold north or northwesterly wind . A spell of anticyclonic weather occurred mid-month across the south, before things got more cyclonic in the last week, with some very intense extratropical lows, one of them being storm Eowyn on the 24th. That’s why I thought it might be interesting to add pentad MSLP charts for January, to show just how anomalies can often times cancel each other out as if nothing had happened.🤔
