Myrskytulvat

Myrskytulvat, also known as storm surges, are rapid rises in sea level caused by strong winds and low atmospheric pressure associated with storms. These surges can lead to significant coastal flooding and erosion. The term "myrskytulvat" is Finnish, translating to "storm waves" or "storm tides." Storm surges are a significant hazard in coastal areas, particularly during tropical cyclones, extratropical cyclones, and other intense storms.

The primary factors contributing to storm surges include the wind setup, which is the piling up of water by the wind, and the barometric setup, which is the change in sea level due to changes in atmospheric pressure. The height of a storm surge is influenced by the intensity and size of the storm, the shape of the coastline, and the local bathymetry.

Storm surges can cause severe damage to coastal infrastructure, including buildings, roads, and utilities. They can also lead to loss of life and displacement of communities. In some cases, storm surges can cause significant changes to the coastline, including erosion and the formation of new landforms.

Meteorological agencies and coastal management authorities often issue storm surge warnings and advisories to help communities prepare for and respond to these hazards. Early warning systems, evacuation plans, and other mitigation measures are essential for reducing the impacts of storm surges.
