Post-tropical cyclone Ophelia to hit Ireland today – update (8:30 UTC)

Severe Weather Europe - 16. Oktoober 2017 - 11:34
Post-tropical cyclone Ophelia will make landfall in Ireland late this morning to early afternoon. Expect a very severe and damaging windstorm with wind gusts peaking at 130-160 km/h, up to 190 km/h at higher elevations. This is a potentially very dangerous situation! Latest airmass view of post-tropical cyclone Ophelia as it nears Ireland. Image: EUMETSAT. Ophelia has transitioned into a post-tropical cyclone, still packing hurricane-force winds: up to 130-135 km/h sustained, gusts well above 150 km/h. Central pressure is 968 mbar and the system is tracking NNE towards landfall in southern Ireland early this afternoon. Various high-resolution models are in good agreement: widespread severe to very severe winds across Ireland, Wales and Northern Ireland gusting at 120-150 km/h, locally up

Warm Monday ahead for parts of western and central Europe

Severe Weather Europe - 15. Oktoober 2017 - 22:41
A very warm day ahead in central and western Europe tomorrow: up to 25-26 °C in BeNeLux, 29-30 °C in SW France and up to 30-31 °C across the Iberian Peninsula. The powerful anticyclone over much of central Europe and the Mediterranean brings stable weather, with clear and sunny skies across much of the continent and very warm temperatures for the season. Temperature inversions with fog may form locally, but mostly erode by early afternoon. BeNeLux Up to 25-26 °C in parts of BeNeLux, and above 20 °C across the entire region. Map: Meteociel.fr. France Warm, up to 24-26 °C across much of the country, up to 30 °C in the extreme SW part of the country. Map: Meteociel.fr. Iberian

Hurricane Ophelia heading for landfall in south Ireland tomorrow

Severe Weather Europe - 15. Oktoober 2017 - 21:40
The currently Category 1 hurricane Ophelia will make landfall in Ireland tomorrow as a post-tropical cyclone packing strong storm to hurricane-force winds. Hurricane Ophelia late on Saturday, October 14, imaged by NASA Terra satellite, then a Category 3 Major Hurricane. Record-breaking Hurricane Ophelia keeps on going strong, currently (Sunday evening) a Category 1 Hurricane, with sustained 145 km/h (90 mph) winds. Ophelia reached Category 3 yesterday, with peak winds of 185 km/h (115 mph). The system displayed textbook hurricane structure and even underwent an eyewall replacement cycle yesterday. Category 1 Hurricane Ophelia late today (Sunday). Image: EUMETSAT. The system will transition into a powerful post-tropical cyclone, making landfall in southern Ireland tomorrow late morning and early afternoon. Latest ensemble forecast

Combination of El Niño and 2016 Ecuador earthquake likely worsened Zika outbreak

ScienceDaily - 13. Oktoober 2017 - 3:02
A Zika virus outbreak in coastal Ecuador in 2016 was likely worsened by a strong El Niño and a magnitude 7.8 earthquake that struck the region in April, according to a new study.

Rainfall trends in arid regions buck commonly held climate change theories

ScienceDaily - 12. Oktoober 2017 - 19:30
To explore the links between climatic warming and rainfall in drylands, scientists analysed more than 50 years of detailed rainfall data (measured every minute) from a semi-arid drainage basin in south east Arizona exhibiting an upward trend in temperatures during that period.

Geologic evidence is the forerunner of ominous prospects for a warming earth

ScienceDaily - 12. Oktoober 2017 - 18:48
While strong seasonal hurricanes have devastated many of the Caribbean and Bahamian islands this year, geologic studies on several of these islands illustrate that more extreme conditions existed in the past. A new analysis shows that the limestone islands of the Bahamas and Bermuda experienced climate changes that were even more extreme than historical events.

Study reveals need for better modeling of weather systems for climate prediction

ScienceDaily - 12. Oktoober 2017 - 16:15
A team of researchers discovered persistent dry and warm biases in the central U.S. that was caused by poor modeling of atmospheric convective systems. Their findings call for better calculations with global climate models.

Scientists develop tool which can predict coastal erosion and recovery in extreme storms

ScienceDaily - 11. Oktoober 2017 - 16:17
Coastal scientists have developed a computerized model which goes some way to answering their subject's 'holy grail' -- how to use existing data to confidently forecast annual coastal erosion and accretion.

Droughts and wildfires: How global warming is drying up the North American monsoon

ScienceDaily - 9. Oktoober 2017 - 19:31
Previous researchers had concluded that global warming was simply delaying the North American monsoon, which brings summer rains to the southwestern US and northwestern Mexico. But a new, high-resolution climate model that corrects for persistent sea surface temperature (SST) biases now accurately reflects current rainfall conditions and demonstrates that the monsoon is not simply delayed, but that the region's total rainfall is facing a dramatic reduction.

Tracking debris in the Earth‘s orbit with centimeter precision using efficient laser technology

ScienceDaily - 5. Oktoober 2017 - 17:38
Uncontrollable flying objects in orbit are a massive risk for modern space travel, and, due to our dependence on satellites today, it is also a risk to global economy. Scientists have now developed a fiber laser that reliably determines the position and direction of the space debris' movement to mitigate these risks.

Numerous waterspouts reported across the central Mediterranean – Oct 3, 2017

Severe Weather Europe - 3. Oktoober 2017 - 11:34
Numerous waterspouts have been reported across the central Mediterranean over the past several days. Reports have come from all coastal areas of Italy, including Sicily and Sardinia as well as Malta. The region has been under the influence of a cold core upper low, providing a favourable environment for the formation of waterspouts. The Mediterranean sea is still warm, with surface temperatures 22-26 °C in the S-CNTRL part. The cold core upper low brings cooler air (currently 10-11 °C at 1500 m and -14 °C at 5000 m). A steep temperature gradient forms and in the absence of significant wind shear this is the typical environment for waterspouts. As the sea surface cooling typically lags behind air temperature drop during
