B4: Regional Storms and their Marine Impacts

CliSAP research topic B4 focusses the most extreme storms in various regions of the Earth, ranging from polar lows in the Arctic, medicanes over the Mediterranean, typhoons or hurricances in the tropics to even the large scale cyclonic weather systems in the extra-tropics. In the centre of interest are their changing statistics and their potential impacts on the marine environment (e.g. surges, waves).

Objectives

Cyclones are usually characterized by inward spiraling winds that rotate anti-clockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere of the Earth.

CliSAP B4 research objectives cover:

  • characteristics of tropical cyclone activities and associated impacts
  • characteristics of European storminess
  • links between storm climates in different ocean basins
  • links to their large scale driving conditions
  • storm induced impacts on the coastal climate and on coastal communities

Subject in these analyses are past, ongoing and expected changes in an anthropogenically warmed world, and the consistency of ongoing change with projections of different future climate scenarios.

Methods

In their research CliSAP B4 scientists combine sophisticated modeling techniques and indirect methods based on storm proxies from oceanic or coastal sediments and on surface air pressure statistics.
