Most people agree that chocolate tastes great, but is there a way to make it taste even better? Perhaps, according to scientists who looked at different conditions that can put a strain on cocoa trees. They say that although the agricultural method used to grow cocoa trees doesn't matter that much, the specific weather conditions do.
Here we go, yet another powerful cold outbreak is expected this weekend as a deep trough coming in from the Northern Europe deepens and digs far south towards the Mediterranean. This is the same trough which will cause the damaging windstorm over Scotland on Thursday, developing an open channel for significant cold advection behind the main frontal system, stretching from the Arctic towards central Europe into N Balkan peninsula and northern Mediterranean. Once the cold front has passed on Saturday, very cold airmass will spread behind it and several days of much colder weather than average are increasingly likely over west-central Europe and N-CNTRL Mediterranean. At coldest, average daily temperatures will in some areas be 10 °C colder than average.Also,
What if there was a better way to forecast and communicate hurricanes' damaging economic impacts, before they happen? Civil engineers have developed an innovative new approach to assessing the resiliency of coastal communities to hurricanes. They've created a 'multi-hazard hurricane impact level model,' which estimates economic damages to be caused by storms, before they happen.
A potentially dangerous setup is forecast for the northern British Isles (mostly Scotland and the surrounding islands) on Thursday. Explosive cyclogenesis (a so-called bombogenesis) is expected to take place north of the Isles in response to a very sharp drop in temperature aloft. As a result, a rapidly deepening cyclone will form from early Thursday morning where central pressure will likely drop from near 985 mb to below 960 mb in less than 12 hours. Pressure gradient across Europe per ECMWF model, map by www.pivotalweather.com Various high-resolutions models (ARPEGE, ICON-EU) are simulating a very dangerous windstorm, where wind gusts could locally reach above 180 km/h or even exceed 200 km/h. Especially severe winds are expected across the higher terrain in
Global models are actually in quite good agreement for the next 10 days where a likely new outbreak of Arctic airmass will be pushed meridionally across Europe next weekend. Indeed it is still 7-8 days ahead and a lot of details is yet to be determined. As far as models are predicting currently, a deep trough would result in several deep cyclones in the Mediterranean, bringing frontal systems with severe weather (excessive rainfall, severe storms, waterspouts, excessive snowfall, blizzard conditions) in some places. We’re closely monitoring the evolution of the pattern through the coming days and will keep you updated. Both GFS and ECMWF (including ensemble forecasts) are simulating a deep trough pushed south towards the Mediterranean which would result
Several of spectacular waterspouts formed over the coast of the Ligurian sea near San Remo, NW Italy yesterday, December 1. The region was under a cold core upper low.

Western Greece and Albania are in for another round of intense rainfall, which is likely to result in significant flooding. High-resolution models suggest locally between 300 and 400 mm of rainfall in the next 3 to 4 days. Map: Pivotal Weather A large cutoff low is forming over the western Mediterranean. Strong and persistent warm air advection in the warm sector will produce ongoing convective and orographic rainfall across the coasts of S Adriatic and Ionian seas and further inland in the mountainous terrain of Albania and NW Greece. Rainfall totals approaching 400 mm are possible in the next 4 days! Total accumulated rainfall by early Monday, ARPEGE model guidance. Map: Wxcharts.eu Total accumulated rainfall by mid-Sunday, ICON model guidance.
New UK map of air pollution provides insights into nitrogen dioxide levels across the country and within towns and cities
Researchers have created the first ever high resolution map of air pollution in the UK. The map shows how air pollution, specifically nitrogen dioxide, changes across the country and within towns and cities, highlighting likely sources and potential clean-air refuge areas.
Sea-level rise may impact vast numbers of archaeological and historic sites, cemeteries, and landscapes on the Atlantic and Gulf coasts of the southeastern United States, according to a new study.
Higher plant species richness may not be enough to protect ecosystems from the worst impacts of climate extremes
Studies on mild fluctuations in weather have provided support for the idea that higher biodiversity results in more stable functioning of ecosystems, but critical appraisal of the evidence from extreme event studies is lacking.
Winter weather is finally here as a large upper trough deepens while moving into central Europe and northern Mediterranean this week. In response to significant cooling aloft, frontal system will form over the Alps and the Mediterranean sea, resulting in several waves crossing countries. Therefore some good amounts of snow are expected until Friday, Dec 1st. One frontal system will be affecting areas from E France across S Germany and Austria towards Czech Republic, Slovakia and Poland, bringing quite a lot of snow in some areas – locally up to 20-30cm is possible, especially above 1000m ASL. Further south across the Alps and NW Mediterranean, another cyclone will be moving and bring excessive rainfall and snowfall further inland. It appears
A wave of cold Arctic maritime air will push into western and central Europe in the next several days, reaching as far south as southern Spain, western and central Mediterranean and into northwestern Africa. Air temperatures at 850 mbar level (~1500 m) will be up to 10 °C colder than average for this period, locally even colder. Map of 850 mbar (~1500 m altitude) temperature anomaly for Friday, GFS model guidance. Map: Tropical Tidbits. In addition to cooler temperatures, the cold push will also bring snowfall to much of central Europe, the northern Mediterranean region. Particularly strong snowfall is expected over the southern Alps, northern Apennines and northwestern Dinarides, as a cutoff Genoa low will form over the northern Meditterranean
An issue of global concern is the anticipated shortage of agricultural output to meet the steady rise in human population. Scientists understand that overcoming crop loss due to disease and adverse weather will be key in achieving this goal.
Researchers have developed a tornado-prediction method they say could buy as much as 20 minutes additional warning time. Using high-altitude turbulence radar can help researchers detect specific tornado signatures, with 90 percent accuracy within a 100-kilometer radius.
Outbreaks of mosquito-borne viruses Zika and Chikungunya generally occur about three weeks after heavy rainfall, research shows. Researchers also found that Chikungunya will predominate over Zika when both circulate at the same time.
A major study looking at changes in where UK birds have been found over the past 40 years has validated the latest climate change models being used to forecast impacts on birds and other animals.
From Trump to Heinz, some of America's most famous family names and brands trace their origins back to Germans who emigrated to the country in the 19th century. Researchers have now found that climate was a major factor in driving migration from Southwest Germany to North America during the 19th century.
Pattern flip coming! This week starts with a strengthening ridge over WSW Europe, gradually expanding eastwards towards central Europe. To the east, deep but weakening trough is maintaining cold weather across the Balkan peninsula and surroundings. This should change in the coming days as an upper ridge / blocking dominates our continent. Once the blocking pattern establishes, a deep longwave trough will move over the N Atlantic and western Europe. Several waves will result in deep cyclones bringing unsettled conditions for the British Isles as well as Faroe Islands later this week. Cyclones will be moving towards the Norwegian coast. Locally very significant rainfall and severe winds associated with these cyclones are likely until the weekend. Areas under the upper
Medicane Numa / Zenon is making landfall on the western coast of Greece this evening. Lefkada, Kefalonia and Zakynthos islands expect strong winds, gusting at well over 100 km/h. Intense rainfall will also accompany the system, locally up to ~100 mm in several hours. As the system approaches the coast, strong convection is encircling the central part / eye of the system. The center of the system is likely to cross over Lefkada island within several hours. Latest high-res model runs suggest peak wind gusts between 110 and 150 km/h on Lefkada, Kefalonia and Zakynthos islands and further inland during the evening. Also expect strong convective with this system, locally up to ~100 mm within several hours. Flash floods are
Medicane Numa / Zenon is now moving southeastward across the Ionian sea for landfall along the western coast of Greece late in the day. We review various high-resolution models. Medicane “Numa” in latest satellite imagery, still located off the southern tip of Italy in the late morning of November 18, 2017. Image: EUMETSAT / Meteociel Latest ARPEGE model guidance indicates the system moving from its current position near the southern tip of Puglia, Italy across the northern Ionian sea towards ESE for landfall over southern Corfu island in the evening hours. The model also suggests the system will strengthen during the day, with peak wind gusts of 120-130 km/h in the second half of the day and at landfall. ARPEGE
