NONLINEAR CHARACTERISTICS OF WAVE HEIGHT IN AN EXTREME WEATHER CONDITIONS

Weather in Extreme Environmental Conditions

Janne Hämäläinen, M.Sc. (Eng.) Product Manager Surface Weather Division Vaisala Helsinki Finland he MILOS 520 Data Collection and Processing System is designed to satisfy the current and future requirements for Automatic Weather Stations that are accurate, reliable and economical in terms of overall costs through the entire life cycle of a system. The MILOS 520 system’s flexible set-up in a Win...

Forecasting wave height probabilities with numerical weather prediction models

Operational weather forecasts now allow two week probabilistic forecasts of wave height. This paper discusses methods for generating such forecasts from numerical model output from the European Centre for Medium Range Weather Forecasting Ensemble Prediction System. The ECMWF system produces Monte Carlo style forecasts of wave statistics out to a lead time of 10 days. This ensemble of forecasts ...

Mooring Line Reliability Analysis of Single Point Mooring (SPM) System under Extreme Wave and Current Conditions

Single Point Mooring (SPM) is a type of offshore facility that is used for the loading and unloading of oil and gas tankers in the sea. In Iran, it is briefly called “floating buoy”. The present study discussed floating type, fixed to the seabed with mooring chain. The mooring chain of SPM, which is considered one of the important parameters of its design, will be evaluated with reg...

Impacts of Snowy Weather Conditions on Expressway Traffic Flow Characteristics

Snowy weather will significantly degrade expressway operations, reduce service levels, and increase driving difficulty. Furthermore, the impact of snow varies in different types of roads, diverse cities, and snow densities due to different driving behavior. Traffic flow parameters are essential to decide what should be appropriate for weather-related traffic management and control strategies. T...
