Building a better weapon against harmful algal blooms

ScienceDaily - 17. Detsember 2018 - 17:18
Scientists have shared early results from a trio of studies that aim to improve models designed to guide agricultural practices for reducing the risk of nitrogen and phosphorous farm runoff. Such runoff leads to the growth of toxic algae in waterways.

Geminid peak night (December 14/15) weather outlook for Europe

Severe Weather Europe - 14. Detsember 2018 - 16:06

Here comes the best Geminid night. Peak rates combine with weekend for a perfect observing opportunity. Let us take a look at the weather outlook across Europe. It appears tonight will be a somewhat better night on average, with larger parts of Europe having a chance for clear skies. In particular the southern and eastern part of the Iberian peninsula looks good – in particular the southern part looks best, while eastern Spain might get some mid-level and high clouds in the second half of the night. The eastern half of France, north Italy and much of Switzerland looks good too. North Italy will be difficult in any case due to extreme light pollution. Some chances for at least partly […]

Windy weekend ahead for the British Isles, Ireland and extreme SW Norway

Severe Weather Europe - 14. Detsember 2018 - 13:21

A succession of relatively deep lows will pass the British Isles and Ireland in the next 2-3 days. While none of the systems will be particularly deep and severe, they will bring intermittent periods of strong to locally severe winds for various parts of the British Isles and Ireland. A broad area of low pressure is developing over the northern Atlantic, west of the British Isles and Ireland. It will bring a number of embedded deep lows across the region in the next 2-3 days. In addition to unsettled, rainy weather and snow in some parts of Scotland, England and Wales and persistent rainfall for Ireland, they will also bring locally very windy weather. Broad area of low pressure over […]

Where to find dark skies for the Geminid meteor shower

Severe Weather Europe - 14. Detsember 2018 - 3:04

Finding dark night skies was easy only two or three decades ago, but lately extravagant and excessive outdoor lighting has spoiled the skies over most of Europe. Light pollution is widespread and increasing rapidly, making it more and more difficult to find good skies to enjoy celestial phenomena like the upcoming Geminid meteor shower. Let us take a look at where we still can find good night skies. The widespread expansion and proliferation of outdoor lighting has degraded the night skies to the extent, where few people actually ever get to experience truly dark night skies. Dark night skies have become rare, in fact several European countries have virtually no dark night skies anymore. There is a common misconception, that […]

Snow over Antarctica buffered sea level rise during last century

ScienceDaily - 13. Detsember 2018 - 21:15
An increase in snowfall accumulation over Antarctica during the 20th century mitigated sea level rise by 0.4 inches. However, Antarctica's additional ice mass gained from snowfall makes up for just about a third of its current ice loss.

Geminid weather across Europe for the night December 13/14, 2018 – where will the meteor shower be best seen tonight

Severe Weather Europe - 13. Detsember 2018 - 16:15

Here come the Geminids! Tonight is the first of two peak nights for this meteor shower as seen from Europe – the peak is expected during the day on December 14 in Europe. Expect over 80 Geminids per hour under clear and dark skies tonight. We take a general look where in Europe the skies tonight will likely be clear and where the best chances of seeing the meteor shower tonight are. While the Geminids are by far the best annual meteor shower, they are also notoriously difficult for observations, as the mid-December weather is often unsettled and many locations are under clouds. Unfortunately, this year is no exception. Tonight the best chances for clear skies will be across parts […]

Snow and locally freezing rain is coming to the British Isles this weekend – December 14-15, 2018

Severe Weather Europe - 13. Detsember 2018 - 13:00

A round of locally quite significant snowfall is coming to the British Isles this weekend. Scotland will receive the most snow, locally up to 10-20 cm at higher elevations. Other parts of the British Isles may receive some snow too, including parts of northern and central England and Wales. We take a closer look. Two deep lows cross the British Isles and Ireland in rapid succession over the weekend, bringing unsettled weather and precipitation to the region. Higher elevations of Scotland in particular and also parts of northern and central England as well as Wales will receive snow. Lower elevations in northern and central England as well as Wales will locally also likely receive freezing rain. Two successive deep lows […]

Record-wet and record-dry months increased in regions worldwide

ScienceDaily - 12. Detsember 2018 - 19:18
More and more rainfall extremes are observed in regions around the globe -- triggering both wet and dry records, a new study shows. Yet there are big differences between regions: The central and Eastern US, northern Europe and northern Asia have experienced heavy rainfall events that have led to severe floods in recent past. In contrast, most African regions have seen an increased frequency of months with a lack of rain.

Researchers mapped the changes in snow mass from 1982 to 2016 onto a grid of squares 2.5-miles on a side over the entire contiguous U.S. Grid size for previous studies was about 40 miles on a side. Since 1982, some parts of the West have a 41 percent reduction in the yearly maximum mass of snow.

Geminid meteor shower life hacks (or: how to have the best view of the meteor shower)

Severe Weather Europe - 12. Detsember 2018 - 1:40

Here are some life hacks we have learned in over two decades of observing meteor showers. Use these and you will be fine and have a great time observing the Geminids! General stuff Get away from light pollution: really, get as far away from light pollution as possible. Bright skies hide many meteors. While you might see 80 meteors per hour under dark rural skies, brighter suburban skies may cut the number to 30 meteors per hour. In urban skies you may be lucky to get 15 Geminids per hour. If you can get to a more remote and higher location in the mountains, you will perhaps see even more meteors. Light pollution goes far: it is not enough that […]
