Europe-wide formation is partly responsible for Storm Daniel, while the north of the continent has high temperatures
An Omega block has been in place over Europe this week, leading to some extreme weather for many. An Omega block is a synoptic setup consisting of a high-pressure region sandwiched between two low-pressure regions, creating a shape resembling the Greek letter omega.
Storm Daniel developed over the Ionian Sea partly due to this setup, causing devastating flooding across central and eastern Greece. The region’s warm seas at this time of year also helped produce the moisture needed for this storm.
