Special Issue "Long Term Climate Variability in the Mediterranean Region"
Deadline for manuscript submissions: 9 July 2020.
Interests: climate variability; climate dynamics; climate reconstruction; historical climatology
Interests: historical climatology; climate dynamics; extreme events; Mediterranean climate variability; seasonal forecast
The Mediterranean region is an area where prediction at different timescales (subseasonal to decadal or even longer timescales) keeps being a challenge. In order to improve future predictions, the study of the past climate is crucial. By improving our knowledge about the past and the current climate, our knowledge about the future climate will be improved. This Special Issue aims to collect as much information as possible about long-term climate variability in the Mediterranean region. We welcome different studies using observations, proxies, re-analyses and models for assessing the characteristics, the main processes, and the variability of the Mediterranean Climate from the past to the future.
Potential topics include but are not limited to:
- The past of the Mediterranean region: from the last millennium to historical climatology in the Mediterranean area (using models, proxies or observations);
- Mechanisms associated with extreme events in the Mediterranean region;
- Compounds events affecting the Mediterranean region;
- Assessing the role of the oceanic and atmospheric modes of variability in the Mediterranean region climate using models, observations or proxies;
- Teleconnections associated to the Mediterranean region;
- The future of the Mediterranean region: from subseasonal to decadal predictions;
- Climate change and the Mediterranean region: attribution studies of extreme events associated to the climate change;
- Risks, vulnerability, and impacts in the Mediterranean region: assessment, mitigation, and adaptation strategies.

Abstract: Tree growth has been proven sensitive to climate variability, which allow the reconstruction of past climate. Drought sensitivity of different trees species may provide reliable information to investigate long-term spatio-temporal rainfall patterns over the Mediterranean Basin, as well as to validate the relationships among different drought proxies. Here, we investigate the drought sensitivity of several long-lived trees (Abies borisii-regis, Abies cilicica, Abies pinsapo, Cedrus atlantica, Cedrus libanii, Pinus nigra, Pinus heldreichii), using tree-ring width data and observed climate. Standardised Precipitation-Evapotranspiration Index (SPEI), North Atlantic Oscillation (NAO), and Westerly Index (WI) were also investigated in order to identify potential non-stationary responses among those drought proxies and climate-growth relationships derived from Dendrochrology. The results indicate that the drought variability, inferred by drought-sensitive trees species (such as C. atlantica), is related to the NAO and the WI. Spatial variability of drought severity suggests a complex association between the NAO and the WI, likely modulated by an east-west Mediterranean climate dipole.
Assessing the Etesian-Indian Summer Monsoon Connection with CMIP5 Models

Abstract: During the summer, the low-level circulation in the eastern Mediterranean is dominated by persistent northerly winds, named “Etesians”, over the Aegean Sea. Several studies have found a significant link between the frequency and strength of these Etesian winds and the strength of the Indian Summer Monsoon (ISM). The Indian summer monsoon pulls heat and moisture to the North driving glacial melting in the northern hemisphere and expanding tropical wetlands that might increase the methane release into the atmosphere generating warmer conditions. Due to the importance of these impacts, further knowledge about the dynamics of this relationship is necessary. Usually, this relationship had only been studied in detail for the second half of the 20th century due to the absence of long and continuous series of observed wind in the eastern Mediterranean for previous periods. However, in the recent study of Gomez-Delgado et al.  a new climatic index "Northerly Wind Index" (NWI) has been created using historical winds records taken aboard sailing ships over the eastern Mediterranean since 1880. In that study, NWI has been used to investigate the NWI-ISM relation in a longer period of time demonstrating that there are two different regimes involved. During the periods of strong positive correlation, the Etesians variability is controlled by two pressure centers, one corresponding to the Asian Monsoon low and the other to the low level high pressure center located over central Europe and the Western Mediterranean. In constrast, when the NWI-ISM correlation fades out, it is the central-west Mediterranean high pressure center which plays the main role in the Etesians variability. In this article we assess the ability of CMIP5 models in reproducing the relationship between the Etesians and the ISM founded in Gomez-Delgado et al. , as well as the impacts in the dynamic of mid-latitudes atmospheric circulation and the future trends in this teleconnection using different scenarios (RCP4.5 and RCP8.5). The effect of spatial resolution is also addressed.
