Live data feeds and weather visualisation

Yahoo produces a rss weather feed based on's forecasts and reports.

There are 47 condition codes, see below for a a full listing. These condition codes are used to describe all the weather conditions across the world. This interactive application has been collecting yahoo's weather feeds since 12.20pm on 21st June 2010.

The problem with visualising live data

Although there are 47 conditions codes to describe all the different weather conditions yahoo only uses about 15 codes to describe the weather conditions in Bristol and over half of the condition codes are either partly cloudy or mostly cloudy. Does partly cloudy give an accurate description of the current weather conditions? There are only two descriptions of rain, drizzle and showers (which is repeated) are they descriptions that enhance our understanding of the weather. Considering how much the weather occupies conversation in England it is surprising that the live data feeds don't a more descriptive report of the weather.

RSS (originally RDF Site Summary, often dubbed Really Simple Syndication) is a family of web feed formats used to publish frequently updated works − such as blog entries, news headlines, audio, and video − in a standardized format. An RSS document (which is called a "feed", "web feed", or "channel") includes full or summarized text, plus metadata such as publishing dates and authorship. Wikipedia
