Abstract Historical trends in the direction and magnitude of ocean surface wave height, period, or are debated due to diverse data, time-periods, methodologies. Using a consistent community-driven ensemble global products, we quantify establish regions with robust multivariate fields between 1980 2014. We find that about 30–40% experienced seasonal mean extreme direction. Most Southern Hemisphere exhibited strong upward-trending heights (1–2 cm per year) periods during winter summer. Ocean...
The term "climate services" is commonly used to refer the generation of climate information, their transformation according user needs and subsequent use information in decision making processes. More generally, concept also involves contextualization knowledge. In following a series examples from marine sector described covering generation, processes while not considered. Examples comprise applications naval architecture, offshore wind more generally renewable energies, shipping emissions,...
Abstract. Six surface drifters (drogued at about 1 m depth) deployed in the inner German Bight (North Sea) were tracked for between 9 and 54 days. Corresponding simulations conducted offline based on currents from two independent models (BSHcmod TRIM). Inclusion of a direct wind drag (0.6 % 10 wind) was needed successful BSHcmod archived 5 depth layer. Adding 50 Stokes drift simulated with third-generation wave model (WAM) tested as an alternative approach. Results resembled each other...
Abstract. Long and consistent wave data are important for analysing climate variability change. Moreover, such also needed in coastal offshore design addressing safety-related issues at sea. Using the third-generation spectral model WAM a multi-decadal wind-wave hindcast North Sea covering period 1949–2014 was produced. The is part of coastDat database representing homogeneous met-ocean set. It shown that despite not being perfect, from generally suitable analysis. In particular, comparisons...
Abstract To investigate relationships between large-scale circulation and regional-scale temperatures during the last (Eemian) interglacial, a simulation with general model (GCM) under orbital forcing conditions of 125 kyr BP is compared forced Late Holocene preindustrial conditions. Consistent previous GCM simulations for Eemian, higher northern summer 2-m are found, which directly related to different insolation. Differences in mean evident such as, instance, stronger winter westerlies...

<ja:p>The methodological framework of a large-scale risk assessment for Austrian forests under scenarios climatic change is presented. A recently developed 3D-patch model initialized with ground-true soil and vegetation data from sample plots the Forest Inventory (AFI). Temperature precipitation current climate are interpolated network more than 600 weather stations to AFI. Vegetation development simulated (âcontrol runâ) starting today's forest composition structure. Similarity species...
Oil dispersed in the water column remains sheltered from wind forcing, so that an altered drift path is a key consequence of using chemical dispersants. In this study, ensemble simulations were conducted based on 7 years simulated atmospheric and marine conditions, evaluating 2,190 hypothetical spills each 636 cells regular grid covering inner German Bight (SE North Sea). Each simulation compares two idealized setups assuming either undispersed or fully oil. Differences are summarized...
Teleconnections of interannual January air temperature variations over four regions are investigated based on quasi‐equilibrium simulations with the general circulation model ECHO‐G for three periods: last interglacial (125 kyr BP ‐ early Eemian); glacial inception (115 BP) and preindustrial period. The simulated teleconnections represent teleconnection component due to internal climate variability in many closely linked signal Arctic Oscillation. hemispheric‐scale structure is robust...
Abstract. Three storm surge events with return periods between 10 and 100 years have occurred in the western Baltic Sea recent (2017, 2019 2023). While most cases such are associated high wind speeds, two of three at relatively moderate speeds. The analysed decomposed into contributions from different factors, as direct atmospheric effects or prefilling Sea, which can lead to extreme water levels. A numerical hindcast simulation is used place their contributing components a climate...
