In this exercise we will use Metview to explore the various ways ensemble forecast can be processed and visualised. The case we will investigate is related to a low pressure system crossing the UK on 10 August 2014: it caused high winds and heavy rain especially in the South-Western part of the country.

 

Info

  • reading and visualising ENS (Ensemble Prediction System) forecasts (in GRIB format)
  • performing fiieldset computations in Macro
  • defining various layouts
  • customising title for plots with multiple fields
