 Presentation

Over the last few years, operators have paid great attention to studies about cross-winds and their attendant risks. The wind characteristics knowledge is essential to ensure the safety of railways and also for wide-span bridges (viaducts, cable-stayed bridges).

Meteodyn is committed to railway and bridge safety as well as improving comfort in outdoor spaces such as stations and their platforms.

YOU ARE...

A Designer or a builder of road or rail infrastructures...

Meteodyn provides you the best information to make the right decisions:

 Optimize wind-related safety for railways and roads
 Improve climatic comfort in your outdoor spaces (stations, passenger platforms etc.)
 Ensure the safety of your road works (bridges, viaducts etc.) and ports (wind safety for users and equipments; aid to boat navigation...)

Software Solutions

Meteodyn has developed automatic CFD software to simulate virtual wind and model this wind in complex terrain and urban area

Expertise and consulting services 

Railways protection

Meteodyn delivers computation and maps of wind characteristics along the rail ways, extreme wind forecasting, aerodynamic and dynamic conduct of train face to know the wind turbulence, wind gust analysis and conception of wind alert systems.

 

 

Real-time wind map in Ports

TopoWind and UrbaWind software packages calculate and determine marine port wind profiles. The former takes into account the effects of the terrain in a large scale (around 30 km2/ 12 mi2) and the latter refines the calculated values around the buildings, light towers, seawalls in a smaller scale (around 1.5 km2/ 0.6mi2).

Wind alert systems

Wind alert systems, based on real-time meteorological measurements, are intended to evaluate the risk of overturning or losing control of the trajectory of a vehicle undertaking a given course. Wind alert systems are intended for the operators who manage the roads/motorways and exposed work sites.

Meteodyn computes the wind characteristics along rail lines with the software TopoWind and programs wind alert systems according to the trains characteristics and the history of the local climatology.

Extreme winds analysis

Meteodyn calculates the extreme wind events, detects and advises the installation of wind screens at high risk sites (viaducts). From our storm database of over 30 years we are able to calculate the return period of Rmax = 1.

Extreme event analysis - Number of Rmax > 1
