Local wind modelling

Local Wind Modelling

For projects planned in mountainous or dessert areas the wind and the wind generated waves, currents and storm surges, may be a critical factor in cost and feasibility.

BMT regularly applies the WRF (Weather Research and Forecasting) model to hindcast data on wind, temperature and precipitation.  We have access to the databases needed to drive the model and the computational facilities and scripts to process large data sets to provide suitable input and hindcast the local conditions. Relevant databases include those describing seawater temperature, land use and type as well as normal meteorological data.

Applications for this include:

  • Hindcasting the ground temperature (in combination with our local 1D ground model) to compute extreme low ground temperature for pipeline design;
  • Hindcasting the daily and extreme wind speeds at LNG terminals situated at the foot of high mountains in areas where violent cold downdraughts occur;
  • Producing design temperature, humidity and precipitation in tropical areas;
  • Providing local wind conditions for the design of flood defence systems in harbours leading to significant savings.

The weather forecasting group of BMT ARGOSS applies the same technology to forecast the conditions up to 14 days in advance for operational planning.
