Cranfield, UK - 110 flying hours


Home-based flying campaigns including:-

  • DIAMET - Diabatic influences on mesoscale structures in extratropical storms, 76 flying hours (11_12)
  • ClearFLo - Clean air For London
  • MAMM - Methane and other greenhouse gases in the Arctic - Measurements, process studies and Modelling
  • COPE - Convective Precipitation Experiment
  • Volcano urgency - Measurements and studies of wind-blown ash over Iceland
  • AQUM - Air Quality forecasting and modelling in the Unified Model


DIAMET

The study of mesoscale structures in cyclonic storms affecting the UK, in response to the NERC AO on 'Storm Risk Mitigation'. The T-NAWDEX pilot flying programme of autumn 2009 was a preparation for this work.

Objectives:

  • Characterising the generation of mesoscale potential vorticity anomalies in cyclonic storms, and their implication for the larger-scale development of the storm and for the effects (e.g. high winds, heavy rain).
  • Understanding physical processes and improving model parameterisations
  • Improving predictability

Meteorological Conditions: Mesoscale structures encompassing fronts, frontal rainbands, secondary (wave) cyclones, sting jets and similar features.

Plan is to fly above the feature of interest and drop a pattern of dropsondes around or across it.  Conduct in situ runs in regions of precipitation to measure the latent heat release. Also boundary-layer flights and flight legs similar to those done for GFDEX to measure air-sea fluxes in conditions of high winds (> 30 kt).

ClearfLo Fellowship


Objectives:

 

  • To provide noveltrace gas measurements to plug the gapbetween urban and regional length scales to assist modelling and satellie validation and facilitate policy making.
  • Data‐mining of VISURB and ADDIENT campaigns–Develop and test ARIES retrieval tools with existing data
  • 20 hrs Met Office time on FAAM aircraft dedicated to this fellowship–ARIES optimised flying in the London plume (cf. ClearFlo)–Complimentary CIMS (Manchester) and FAAM core in situ measurements for validation
  • Collaborate with currently funded projects (e.g. ClearFlo – NERC strategic programme)
  • Input and analysis using the CMAQ regional air quality model (Herts)



COPE

 

Aim: To improve forecasts of heavy precipitation leading to flash flooding by understanding the physical processes and rates of those processes in the formation and development of precipitation.

Objectives:

  • Determine the microphysical processes and rates of development of precipitation from the initiation stages through to intense precipitation responsible for flash flooding, and hence improve the physics in the models;
  • Determine the dynamics and thermodynamics of the particular clouds that develop and persist, and hence improve the physics in the models;
  • Assess representation of convection with models at various storm-resolving resolutions;
  • Determine improvements made in the prediction of convective rainfall by assimilating moisture, air motion and radar reflectivity data on the mesoscale and convective scale;
  • Understand the predictability of convective rainfall in the UM and the dominant sources of model uncertainty and error.
