temperature series in the world. By collating and combining early instrumental records, the series charts monthly temperature statistics from 1659. The series is representative of a region enclosed by Lancashire, London and Bristol.  Cooler and warmer spells When looking at the series you can clearly see

, the manually drawn T+24 SIGWX forecast charts that they will replace. It is important to note that the manually drawn T+24 SIGWX forecasts are not considered to be “the truth” and the new SIGWX forecasts aren’t trying to be identical to them, instead both are verified against observational data sets

icing severity, and turbulence severity data will be produced using exact pressure levels • For example FL100 is calculated using data for 696.8hPa and not 700hPa. This is in preparation for future changes where icing data will be provided at 1000ft intervals. • Where the flight level is below

, Nottinghamshire and the West Midlands. Parts of central England experienced extreme rainfall in late September from three successive low pressure systems. The Oxford Radcliffe Observatory recorded its wettest 2-day period in a near 200-year daily record and wettest calendar month since 1774; some locations

-coded layers. Can METARs/TAFs be easier to read? A decoded or better formatted output would help. Can I get a better visual for wind data? Can I click the map to get actual values? It’s hard to interpret just colours. How can I easily print or save the official charts (e.g. F214/F215)? Where is the page

the descriptive text. The full volume of plates is available from our Digitial Library & Archive. These include a large scale chart showing the routes of all three voyages and a large collection of plates showing both the locations he visited and most especially the native peoples he encountered. The plates provide a fascinating insight into the differing cultures of the pacific populations in both the northern and southern hemisphere.        

Explanation of detail in F215, 26 th July 2017, valid 0800-1700 UTC 1. Basic Principles The basic principle of the F215 chart is to provide as detailed a forecast as possible in the space available. This gives rise to the use of abbreviations. It is appreciated that there are many abbreviations
