The dying winds

[Skybird]

Not sure whether I just wanted and planned to post this some days ago, or actually did post it in some thread, at least I do not find it. So I post it here (again?). Interesting, desillusionizing.

"The westerly wind weather, which has provided northwestern Europe and Central Europe with sufficient precipitation for as long as we can remember, has been artificially switched off." says the historian and author Dagmar Jestrzemski. She has been investigating the drought problem of the past few years and has found a possible surprising cause. The westerly wind weather conditions, necessary for rain and plant growth, are increasingly absent. She sees the high density of wind turbines in Germany as responsible, which causes increasing problems with moisture transport in the lower atmosphere: -

Declining wind speeds for Germany are testimony to the results of a study published by Deutsche WindGuard on October 5, 2020 on behalf of the Bundesverband WindEnergie e.V. with the title "Full load hours of wind turbines on land - development, influences, effects". - According to this, the mean specific nominal power of the wind turbines (MSN) - the ratio of the nominal power of the wind turbines to their rotor circular areas is measured - steadily deteriorated in Germany from 2012 to 2019 and this, although wind energy has been more and more effective for 20 years and now from heights significantly above 200 m is skimmed off. -

The cause of the trend, which is worrying for the wind industry, is the decline in the mean wind speed in Germany, which has been measured for decades. Despite the hoped-for increase in energy yield due to the steadily increasing effectiveness of the wind turbines, the MSN in Schleswig-Holstein fell by around 30%, in the north by 25%, in the middle by 23% and in the south by 26%. Specifically, it concerns the decrease from 420 watts / sqm to approx. 295 W / sqm in Schleswig-Holstein, from 400 to 300 W / sqm in the north, from 380 to 270 W / sqm in the middle and from 380 to 280 W. / sqm in southern Germany. -

The study by Deutsche WindGuard shows a relatively stronger decrease in the mean annual wind in those regions where the wind blows comparatively the strongest and the wind energy is accordingly most intensively siphoned off. For the whole of Germany, the result of this study establishes a clear connection between the declining wind speed and the massive extraction of wind energy from the atmosphere: -

The wind farms fall victim to an atmospheric calming wind that they have generated themselves. - A study published more than two years ago by the “Institute of Atmospheric Physics, the Chinese Academy of Sciences” (Huang et al.), Beijing, came to the conclusion that the continuous decrease in atmospheric wind in the northern hemisphere is a widespread and widespread is now a potentially global phenomenon. The phenomenon is also known as “global terrestrial stilling”. In China, the country with the world's strongest wind power capacity, the regions with gigantic commercial wind farms in areas with large wind energy reserves consistently recorded the greatest declines in near-surface wind energy. In Europe too, 50 percent of the stations observed have lost more than 30 percent of the wind power potential since 1979. -

This trend, which has persisted for 40 years, is in contrast to the "investigations of the geostrophic winds over the German Bight since 1880. This revealed periods of weaker and stronger winds, between which 20- or 30-year decreases or increases are discernible". - Accordingly, a reversal of the declining wind development should have occurred long ago. This is by no means indicated. A factor must therefore be effective here that prevents the reversal of the negative wind trend, so that the continuous decrease in mean wind speeds continues. -

For Schleswig-Holstein there is also the fact that, according to the IWR Wind Yield Index, the wind has decreased particularly strongly on the coast, between 2008 and 2017 by approx. 7%, in the interior of the country by only approx. 5%, both compared to the decade before. The greater decrease in wind speed on the coast - compared to the inland - is likely to be attributable to the wind shading effects of the North Sea wind farms and the particularly numerous coastal wind farms. -

Obstacles do not directly draw energy from the wind. Only the turbulence that occurs there withdraw energy from the air flow. In contrast to this, a significant part of the wind energy (max. 59.3%) is directly siphoned off and consumed when generating wind power. The slowed and turbulent currents (dragging wind) in the lee of the wind turbine also withdraw energy from the wind - on land up to a length of 30 km, over the sea up to 100 km. Both effects inevitably slow down the wind across large regions. -

The siphoned off wind, which is increasingly lacking in more and more locations and therefore to an increasing extent in regional and global wind systems, has catastrophic consequences: Less wind = less rain = drought and dry soil, forest death, crop losses = less spread of pollen and seeds = less rejuvenation of the Vegetation. -

In Germany, with its 30,000 inland turbines and around 1,600 offshore wind farms, there are hardly any regions of sufficient size for the natural atmospheric currents to recover from the braking effect of the wind farms. As a result of the strong concentration of wind farms, the warmer soil air in these regions can no longer rise at night, so that a comparatively higher rise in temperature was provoked in Germany (Confidential communications from politics, business and investment, No. 4356, regarding: D. Keith & Lee Miller, Joule 10/04/2018). For 2018, a temperature increase of 0.24 ° C was calculated, which is above average in a European comparison, which is attributed to the 30,000 wind farms on land. -

In January, German Watch announced: Germany ranks 10th among the countries most affected by climate change (= temperature rise, drought). Why Germany of all places? Climate activists ask themselves, who simply do not want to consider the real cause. Answer: Because in this country, in relation to land and sea area, most wind turbines have been installed worldwide. Weeks or months of drought have been the norm here in the Hamburg area for a number of years almost all year round. As a result, we notice an unprecedented calm in the formerly windy north, now also in autumn and winter. No more heavy rain and “bad weather” only for a few days - these are part of the symptoms of the dwindling wind. -

Especially at night, the wind farms on land prevent a drop in temperatures. The warming caused by static permanent high pressure areas over Germany did not stop at the borders. This is confirmed by a message from the Royal Netherlands Meteorological Institute dated January 5th, 2021: “The temperature in the Netherlands has risen by an average of 1.1 ° C over the last three decades (!!). That is more than twice as much as the increase in the global average temperature in the same period. "-

Wind brings rain. Site-specific withdrawal of wind energy has already intensified climate change instead of containing it: Weakened Atlantic low pressure areas during the growth period free the space for static high pressure areas and thus cause an existence-threatening loss or even a drying up of precipitation as in 2018 in Germany and some neighboring countries. The fact that this connection is still not recognized or underestimated by the responsible body is based on the fatal misconception that wind energy extraction is not harmful to the climate, regardless of the extent. -

Wind and water are two inseparable resources! Politicians, scientists, journalists and those interested in the wind industry also know that the siphoning off of wind energy is related to the increasingly pronounced wind calming. Actually, those responsible should be clear that a continued exponential expansion of wind energy, as it is planned on the basis of the European "Green Deal", means switching off the natural wind balance, which will very soon lead to a catastrophe - if the catastrophe does not already exist for us has caught up! The drought that has suddenly become virulent over the past three years should serve as the very last warning to all those responsible. -

The temporal connection between the exponential expansion of wind power capacity in Germany and the outbreak of the severe drought - with an unprecedented water shortage during the growth period - 2018, 2019 and 2020 to be taken seriously: 2010: 26.86 GW, 2014: 38.16 GW, 2017: 53.3 GW each on land, 2019: 61.3 GW and 2020: 65.3 GW wind power capacity on land and offshore. - Regardless of this, politicians and the wind industry are planning a further exponential expansion of WE capacity on land and above all offshore: 300 GW in the North and Baltic Seas alone. That would undoubtedly mean the death of the marine environment in the North Sea and large parts of the Baltic Sea. In fact, expanding the WE would act like a fire accelerator for the drought that caught up with us in 2018. -

In Germany and all of Europe there is still a taboo regarding cause and effect, i.e. a refusal to recognize the connection between the exponentially operated wind energy extraction and the wind lull that is provoked by it. The weakened wind, in turn, intensifies climate change by freeing up space for static high pressure areas and weeks of droughts for most of the year. [Guest author Dagmar Jestrzemski]
