Cloud Banding and Winds in Intense European Cyclones: Results from the DIAMET Project
in Bulletin of the American Meteorological Society
Description | We have made rare measurements of air-sea fluxes of heat, moisture and momentum during storms around the UK. We have used these observations to validate the algorithms used in numerical weather forecasting models, including that used by the UK Met office. These are broadly within the range of the observations. We have found a significant difference in observed fluxes in along and across wind directions, i.e. there is mesoscale structure in the flux fields, which is dictated by the weather system. We have looked at the distribution of air-sea flux fields in the North Atlantic and found that the Iceland Sea is a local minima of ocean-atmosphere exchange. We've explained why this is the case. |
Exploitation Route | Our findings have been used by several other colleagues in their studies of weather system dynamics. |
Sectors | Environment |
Description | Results from the DIAMET project (Cook and Renfrew 2015) were used to evaluate several air-sea flux parameterisations, including those used at the Met Office and at ECMWF. These generally performed well, so no action was needed. This evaluation was useful in establishing quality and appropriateness of these parameterisations. |
