A Different Kind Of Turbulence

By Miguel Teixeira It might be thought that turbulence is essentially the same everywhere. However, its mixing efficiency depends not only on its intensity (as might be expected intuitively), but also on more subtle properties, such as its anisotropy (which … Continue reading

Skirting the Issue

By Geoff Wadge During a major explosive volcanic eruption a set of three main processes transfers mass and heat from the solid earth to the atmosphere. These three processes are: a gas thrust (jet) extending up from the volcanic vent, … Continue reading

The physics behind a physics scheme

By Alan Grant When I joined the Met Office (or, as it was then, The Meteorological Office), I was posted to the boundary layer group. I spent a number of years investigating the atmospheric boundary layer, using data from aircraft … Continue reading

How can a hurricane near the USA affect the weather in Europe?

By John Methven It may seem bizarre that processes occurring within clouds near the USA, involving tiny ice crystals and water droplets, can have an influence on high-impact weather events thousands of kilometres away in Europe, and our ability to predict them … Continue reading

Improving jet stream forecasts through observational experiment

By John Methven Weather systems developing over the North Atlantic and hitting Europe are intimately related to large-amplitude meanders of the jet stream, known as Rossby waves. Characteristic weather patterns grow in concert with the waves, and the jet stream … Continue reading

How do solar eclipses affect the weather?

By Suzanne Gray     Department of Meteorology On the morning of Friday 20 March 2015 a rare near-total solar eclipse will occur in the UK. Why do meteorologists, as well as astronomers and amateur scientists, have the day marked on their calendars? … Continue reading

Reconstructing space climate

By Matt Owens The approximately 11-year cycle in the number of sunspots visible on the Sun was first identified more than 150 years ago, by Samuel Schwabe, and has been well-observed ever since. In fact, with the power of hindsight, … Continue reading

Heating up for a new academic year

By Maarten Ambaum When most “normal” people are enjoying their holidays, many academics are gearing up for the next academic year. Come October, when our new students sit expectantly in the lecture halls, we need to present them with the … Continue reading
