Trading Evil lasers for MAGIC Doppler lidars

By: Janet Barlow  Lasers may have an evil reputation in Hollywood, but they are very good for observing urban meteorology. We recently took part in the MAGIC project field campaign in London, deploying a Doppler lidar to measure wind-speed around … Continue reading

Challenges in the closure of the surface energy budget at the continental scale

By: Bo Dong Since satellite observations began in the late 1970s, our knowledge of energy flows in and out of the Earth’s climate system has been greatly advanced. Taking advantage of state-of-the-art Earth Observation (EO) programmes such as the Clouds … Continue reading

Can observations of the ocean help predict the weather?

By Amos Lawless It has long been recognized that there are strong interactions between the atmosphere and the ocean. For example, the sea surface temperature affects what happens in the lower boundary of the atmosphere, while heat, momentum and moisture … 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

Mountain waves, ship waves and duck waves

By Miguel Teixeira There is a striking resemblance between some waves generated in the atmosphere in flow over isolated mountains and wave patterns in the wakes of ships, boats, or even ducks swimming in a pond. Typically, these waves are … Continue reading
