Objective Lamb Weather Types – June 2020

I hadn’t realise until I ran the analysis on the objective LWT data from the CRU just how cyclonic June 2020 had been. It’s the joint sixth most cyclonic June in LWT circulation types since 1871, thats 150 June’s if I’m not mistaken. It’s in very good company because that exactly the same index as June 2019, in fact there’s a fair old number of Junes from the 21st century in that ranked list of cyclonic June’s. The linear trend suggests that Junes have been getting very slightly more cyclonic in nature since 1871 but that you’d notice.
