Coastal Climate

Environmental conditions such as storms, storm surges or extreme wind generated waves at the sea surface considerably influence living and working at sea and in coastal areas. Coastal climate is the statistics of such events.
Scientists from the coastal climate group analyze the state, variability, and long-term changes of the coastal climate. Using complex numerical models the scientists reconstruct recent changes and variability, and develop scenarios for future developments. The objective is to gain improved understanding of climatic processes and their changes in the coastal system supporting the scientific community, the general public, public authorities and businesses interested in coastal climate in decision making.
Regionally the activities are presently focused on the North Sea and the Baltic Sea while others coastal areas such as in Southeast Asia increasingly receive attention. A core product of the group’s activities is the coastDat data set which is presently applied by more than 100 users.

Storm Surge Monitor

The storm surge monitor developed by scientists from the Institute for Coastal Research at the Helmholtz Zentrum Geesthacht provides information about changes in the storm surge climate in the North and the Baltic Seas over the past decades.

It shows if and to what extent the current season is unusual when compared to previous years. For this purpose, we analyze near-real time tide-gauge measurements provided by the responsible authorities on PEGELONLINE and relate the data to long-term statistics developed at the Helmholtz-Zentrum Geesthacht. Our analyses are updated once a day. Storm Surge Monitor
