Накратко на български

Скоростта на вятъра в умерените ширини намалява, което се проучва чрез анализ на исторически данни от преди 1960 г. Разбирането на този процес помага за по-добри прогнози за климата и влиянието му върху енергетиката, земеделието и качеството на въздуха.

Towards improved understanding of the worldwide decline of wind speed in a climate change scenario

Wind speed has declined over mid-latitude regions over the past 50-years, a phenomenon known as “stilling”. Scientists have paid little attention on the study of the causes behind wind changes, and are divided to how global warming is impacting wind speed changes. The identification of the exact cause(s) is still unresolved and, therefore, the overall objective of this action was to better understand the current slowdown of winds in a changing climate by filling the key gap of short availability (since the 1960s) and low quality of instrumental records. Improving our knowledge on wind speed changes is of great scientific, socioeconomic, and environmental interest to advance climate change adaptation. For instance, the “stilling” phenomenon impacts a wide array of spheres, including: (i) wind power generation; (ii) agriculture, forestry, and hydrology due to evapotranspiration; (iii) air quality and impacts on human health and environment; (iv) wind damage propagation in forest; and (v) migration of wind-dispersed plant species, among others. The STILLING project addressed one of the major constraints to assess wind speed variability with high confidence: i.e., the quantity and the quality of wind speed observations to allow a reliable study. This action rescued, quality-controlled and homogenized historical wind speed data for long-term time-scales never explored before (prior to the 1960s), and improved our understanding of wind speed changes in the past. These kind of investigations that look at past wind speed changes are crucial to better assess future wind speed projections. The results of this MSCA action have shown new evidences on e.g. the impact of the degradation of anemometers on wind speed measurements; the climate variability of winds and the influence of atmospheric circulation for a hot-spot region such as the Canary Islands (Eastern North Atlantic region) since the 1940s; and the wind speed changes worldwide during last decades. The STILLING project has consolidated a novel research line on the study of wind changes, and has raised new research questions to be investigated in the future: are extreme wind gusts also declining in line with the “stilling” for mean wind or more frequent and severe wind gusts are occurring due to a changing climate?.

Цел на проекта

In a globally changing climate, scientists have paid little attention on variability of wind speed. A recent discovery to science is the “global stilling""; a worldwide slowdown of wind speed since the 1980s. This stilling is not fully understood and neither the quantity nor the quality of wind speed observations is adequate to allow a reliable study. The scientific aims of this MSCA to fill this key gap are (i) to rescue the longest wind speed series (starting prior to the 1960s), and (ii) to improve our knowledge on the influence of atmospheric circulation. Given the interdisciplinary impacts of ""global stilling"" on wind energy, agriculture and hydrology, the socioeconomic-environmental aim is (iii) to look at past wind speed to better assess future wind speed projections needed for climate change adaptation. The innovative approach combines the rescue (ACE framework) and homogenization (SNHT test) of historical wind speed data, providing a unique opportunity to statistically assess trends/cycles and atmospheric causes (SOM/RCPA and weather typing techniques) on long time periods and reliable datasets than previous studies. The applicant will bring his new homogenization protocol, extensive expertise on winds and a novel collaboration topic to UGOT and KNMI. In turn, these Institutions are world authorities on data rescue techniques and attributing causes of climate trends; the applicant will also be trained in leadership, management, funding, supervision and communication skills enhancing his career development. Jointly this team is in a position to push the boundaries of “global stilling” knowledge far ahead, with the ultimate intent to allow the applicant to train through research, establish an independent career, and a research group at the forefront of wind research in Europe. Additionally, this MSCA addresses two of the H2020 Societal Challenges: “Secure, Clean and Efficient Energy”, and “Climate action, Environment, Resource efficiency and Raw materials”.""
