My research is focused on atmospheric convection and its role in Earth's weather and climate. A list of my publications is available.
Current funded projects include:
The South AMerican Biomass Burning Analysis (SAMBBA)
The Convective Storm Initiation Project (CSIP): Further Analysis - NERC
AMMA II: African Monsoon Multidiscplinary Analysis II - NERC
Fennec: The Saharan Climate System - NERC
Desert Storms - ERC
A seamless approach to assessing model uncertainties in
climate projections of severe European windstorms - Axa Insurance
DIAMET: DIAbatic influence on Mesoscale structures in ExTratropical storms - NERC
Jan 2009 - present
I am working on convection as part of the
National Centre for Atmopsheric Science (Weather). My current research interests include deep convection, cloud-aerosol interactions in convective clouds, convective processes in West Africa and Saharan dust uplift and transport.
July 2007 - Dec 2008:
I worked with
Prof Alan Blyth ,
Prof Doug Parker and Prof Keith Browning on a
NERC funded project analysing data from the
Convective Storm Initiation Project
(CSIP).
I also took part in the GERB Intercomparison of Longwave and
Shortwave radiation (GERBILS) project, studying dust uplift and transport
in the Sahara.
July 2004 - June 2007:
I was working with on the NERC funded consortium,
the Convective Storm Initiation Project
(CSIP).
April 2003 - June 2004:
The effects of wind-shear on cirrus clouds with
Dr Steven Dobbie .
October 2000 - February 2003:
My PhD at Edinburgh University,
''Lake temperatures - thermal
remote sensing and assimilation into a lake model'' (a copy of my thesis
is available from my list of
publications ).
I am currently teaching an introductory IDL course. This is to some extent based on Hugh Pumphrey's (University of Edinburgh) IDL course. Notes are available (note icons at top left that step forward/back through these). Data used in the course are available (please note that is still work in progress).
Although these notes are a step-by-step introduction, I would also encourage people to look at the numerous examples in Andy Heap's (Centre for Global Atmospheric Modelling, The University of Reading) An Introduction to Using IDL in Meteorology. --- these notes contain some more sophisticated examples and also a good summary. There is also an online preview of IDL programming techniques available, as well as paper books (such as Practical IDL Programming by Liam Gumley). It's also worth looking at David Fanning's site , e.g. his slow-loops tutorial. If you do atmospheric science, Dominik Brunner's Basic IDL routines for atmospheric science are really useful. Once you think that you've really got IDL sorted you could always join the IEPA ! None of these notes really cover good and bad practise in scientific programming. For that you might want to consult Jason Lander's notes on How not to write a computer program.For pretty pictures of clouds (including clouds that look like things) see The Cloud Appreciation Society.
