SEVERE WEATHER PHOTOGRAPHY IN MID WALES - WELCOME TO JOHN MASON'S WEB SITE ....dedicated to all aspects of Welsh weather but especially to storm-chasing - the art of deliberately intercepting thunderstorms, floods, tornadoes, hail, blizzards and the like, armed with a camera and a certain amount of caution! Last updated 24:08:2010. Wales has a "tabloid" reputation for just being wet all of the time. To put it politely this is totally untrue! We have an amazingly varied climate here, from the tranquil beauty of a seascape summer sunset to the full fury of an autumn "Atlantic Bomb" cyclone. The combination of the beautiful landscapes and dramatic things going on in the skies overhead is enough to challenge any serious photographer.

Slide-Library index - click HERE John's ongoing Welsh Weather Photo-diary The diary pages, started in about 2000, are the product of my passion for Wales, its landscapes and its weather - and also of the steep learning-curve I have spent the last 7 years upon in pursuit of the complex science of meteorology and forecasting. It currently contains 151 pages of wild and not-so-wild weatherpix, stormchase accounts and weather-related information - so, while the rain hammers against your window on a winter's night - enjoy Mid-Wales, its seasons and its weather!   John, Machynlleth, Mid Wales.

	TORRO - the Tornado and Storm Research Organisation - is a privately supported research body, serving the national and international public interest. Founded in 1974, data-collection, research and co-ordination is undertaken by the Directors of TORRO, supported by some 400 observers, investigators and other contributors. Most supporters are British, with a smaller number from elsewhere in Europe and across the world. Work by all TORRO personnel - the Directors (of which I am one), Executives, European Representatives - and all members and supporters is undertaken voluntarily. TORRO Staff are composed of professional and amateur meteorologists, with academic qualifications ranging from nothing to doctorates: the only requirements are an interest in the subject area, enthusiasm and a desire to add to the body of scientific knowledge relating to our changeable and at times spectacular climate.
