The data for this year has finally started to flow again from the CRU at the UEA. I thought I would smarten up the UIUI User Interface for my Jenkinson LWTLWT Lamb Weather Types are often used in UK-based analyses, with individual weather patterns based on the eight primary cardinal directions (N, NE, E, SE, S, SW, W, NW) plus cyclonic (C), anticyclonic (A) and unclassified (U) types. application and also add a few embellishments. Above is a screenshot of the latest version, showing the last three months from the latest data they have for downloading on the 19th of February. As you can see the last three months have been quite an anticyclonic affair, but also generally zonal in nature, a part from a spell of easterlies from the 7th to the 19th of February. The 12 UTCUTC Coordinated Universal Time or UTC is the primary time standard by which the world regulates clocks and time. It is within about 1 second of mean solar time (such as UT1) at 0° longitude (at the IERS Reference Meridian as the currently used prime meridian) and is not adjusted for daylight saving time. It is effectively a successor to Greenwich Mean Time (GMT). reanalysis data the CRU use to generate their LWT indices with, didn’t manage to make the GIGI Gale Index anything higher than 53.7 for Storm Eowyn on the 24th of January, although my Objective LWT application, which uses 6 hourly reanalysis data, did manage to find a very high GI of 71.7 at 06 UTC on the 24th for 55N 5W. That would make it the second highest six hourly GI on record since reanalysis records began in 1871, and second only to the massive 85.8 from the great Ochertyre storm of 26th January 1884. I’m still working on that application, but hopefully will post something about it as soon as I’ve cleared some of the outstanding bugs in it up.
