Kilovolt Low pressure Situation
Blocks in meteorology are large scale patterns in the atmospheric pressure field that are nearly stationary, effectively "blocking" or redirecting migratory cyclones. They are also known as blocking highs or blocking anticyclones.[1] These blocks can remain in place for several days or even weeks, causing the areas affected by them to have the
