What makes a good maritime weather forecast?

Even though weather may seem like a minor consideration in maritime operations, a high-performance forecast can save time and money, and can be the difference between meeting your operational goals on time or falling behind.

At Infoplaza we work around the clock on optimizing our weather and wave forecasts in order to provide our clients with high-end data and the best associated risk analysis possible. But what makes a maritime weather forecast really stand out? And how do we come to reliable products capable of supporting all kinds of naval operations? Let’s find out now.

Increased computing power

Nowadays, atmospheric models and their continuously increasing computing power form the foundation of virtually all weather and wave forecasts. These models provide highly detailed atmospheric parameters worldwide, which drive our wave models to simulate long-period swells, shorter wind-driven waves, and related wave parameters based on the predicted atmospheric conditions.

 

Usually, this model output is very reliable for locations in rather deep water far offshore where wave energy is transmitted freely without interference of shallows or coast lines. To solve the physical processes that affect the different wave systems in shallow coastal waters or near complex bathymetry, we run multiple high-resolution inhouse models which can be tweaked to match the bathymetry, shape of coast lines and river mouths perfectly. This way processes like refraction, shoaling and diffraction as well as breaking and dissipation are modelled strikingly accurate.

Human interaction is what really makes the difference

With this high-end model output the forecast is however, only as good as the model’s performance. Eventually it is the postprocessing, data analyses and clear client specific communication done by our experienced meteorologists, that makes a maritime forecast really stand out.

The forecaster will always compare the vast amount of model data against observations in the vicinity of the worksite to improve performance for the specific location and adjust the model output to closely match local conditions. Moreover, continuous verification ensures that the maritime forecast you receive is accurate, reliable, and fully optimized for your operations.

 

 

By versatile, timely and clear communication, we are able to let bad weather only affect your operations for as short a period as possible. In other words, we help you significantly reduce downtime and guide you toward the decision point at the right time. Because ultimately, your safety and the continuity of your offshore operations are what matter most to us.
