Consulting
Acting as a Consultant, Lead Scientist or Analyst, Dr. Bradley Jemmett-Smith is well placed to help you with projects related to the Geosciences, particularly Climate Change, Meteorology and Earth System Science.
Dr Bradley Jemmett-Smith brings a rare and comprehensive academic background in Geosciences, holding a PhD in Meteorology, an MRes in Physics of the Earth & Atmosphere, and a BSc in Earth System Science. His research has made meaningful contributions to the scientific community, with published work available to view here.

COLPEX
The science of nocturnal boundary layers. Nocturnal boundary-layers remain one of the most under-researched areas of Meteorology. Research has generally focused more on day-time weather, with night-time weather being somewhat neglected in comparison.
Why is this improtant?
Night-time minimum temperatures remain a key metric of weather and climate, subsequently, models need to be able to represent minimum temperature. Further to this, the preceeding night-time weather impacts the following day-time weather. You cannot accurately predict one without the other.
The Cold Air Pool Experiment (COLPEX) aimed to better understand and subsequently represent night-time boundary-layers in operational weather models, specifically cold air in valleys. The project was a collaboration of scientists from the University of Leeds, Met Office and National Centre for Atmospheric Science (NCAS). The project culminated in numerous publications, including:
Summary paper about the project: “COLPEX: Field and Numerical Studies over a Region of Small Hills”
One of the few Climalotigical studies ever conducted on the subject: “A short climatological study of cold air pools and drainage flows in small valleys”
A detailed investigation of nocturnal boundary layer evoloution in a UK valley: “A case-study of cold-air pool evolution in hilly terrain using field measurements from COLPEX”, see illustration below.
Desert Storms
The core objective of this project was to explore ways of better representing crucial meteorological processes in numerical dust models. My focus was on the interesting Meteorological phenbomena of Dust Devils.
The project culminated in numerous publications. Contributions included:
Only the second global estimate of dust uplift contribution caused by Dest Devils up to the time of publication, and the first to use global meteorologiocal model data to quantify their occurence. The work highlighted a potential large overestimation of dust devil influence on the global dust budget:
“Quantifying global dust devil occurrence from meteorological analyses”
“Dust Devils” a book by Springer, part of the International Space Science Institute series of books. I contributed to three chapters in this world leading book about the meteorological phenomena of Dust Devils.
