VALID FOR 05-04-2018 SYNOPSIS Dynamic weather pattern across Europe on Thursday, a short-wave moves across central Europe with a surface frontal system affecting N Mediterranean and Balkan peninsula. Further west, deep trough/cyclone is located across eastern Atlantic, while a strengthening ridge is spreading across WSW Europe. Large cyclone with cold weather remains across northern Europe. DISCUSSION A SLGT risk has been issued for parts of central Balkan peninsula including E-CNTRL Bosnia and S-CNTRL Serbia with threat for isolated severe storms, capable of producing marginally large hail, severe winds and torrential rainfall. Marginal to moderate instability will be available ahead of the approaching cold front within moderate deep-layer wind shear. Although the upper-level forcing will be rather strong and widespread shallow
Rising anthropogenic, or human-caused, carbon dioxide in the atmosphere may have up to twice the impact on coastal estuaries as it does in the oceans because the human-caused CO2 lowers the ecosystem's ability to absorb natural fluctuations of the greenhouse gas, a new study suggests.
Weather extremes caused by climate change could raise the risk of food shortages in many countries, new research suggests.
VALID FOR 01-04-2018 SYNOPSIS A pronounced trough is gradually weakening while moving from central towards the eastern Europe. At surface, a cold front is pushed across S Balkan peninsula. Another trough is approaching Iberia from the Atlantic while ridge builds in between across the Mediterranean. DISCUSSION SLGT/MRGL risks have been issued for parts of NE Italy, Slovenia and NW Croatia with threat for isoalated marginal hail and heavy rainfall. A few 100 J/kg of MLCAPE builds up across the risk area within moderately strong wind shear. Conditions are supportive of organized storms and widespread graupel showers mainly in the afternoon hours. SLGT risk has been issued for parts of S Balkan peninsula including S Serbia, Albania, N Greece, Bulgaria and
VALID FOR 31-03-2018 SYNOPSIS A large trough centered over west-central Europe dominates our continent with a frontal system pushed across the north-central Mediterranean and N Balkan peninsula. A cold front expected to bring severe weather into some regions as airmass become marginally to moderately unstable across the large warm sector. Strong warm advection is expected across the SE Europe while cold weather remains across NNE Europe. DISCUSSION An ENH risk has been issued for S Hungary, most of Croatia, Bosnia & Herzegovina, NW Serbia, extreme SSW Slovenia and ENE Adriatic sea with threat for severe storms capable of producing severe winds, large hail and torrential rainfall. A cold front pushes through the risk area during the day and evening hours
VALID FOR 30-03-2018 SYNOPSIS Europe is dominated by a large upper trough spreading into central Europe with a surface frontal zone moving east through Friday. Very cold mid levels spread across the Bay of Biscay. DISCUSSION A SLGT risk has been issued for parts of N Italy, N Adriatic sea, W Slovenia and NW Croatia with threat for excessive rainfall due to continuous orographic precipitation combined with some convection. Locally more than 100 mm is expected in 24 hours. Additionally, strong warm advection should result in weakly unstable airmass (MLCAPE of near 400-800 J/kg) within strong (25+ m/s) deep layer shear and good helicity across the N Italian plains. Some severe storms could be possible in the afternoon hours, mainly
New study from the West Greenland Ice Sheet shows that weather patterns and summer warming combine to drive ice loss that is at the highest levels in at least 450 years.
VALID FOR 29-03-2018 SYNOPSIS A large trough over W Europe is advancing towards SE through Thursday with a surface front pushed towards central Europe. High pressure system remains over NE Europe while a short-wave through over SE Europe is weakening and moving further NE towards Georgia through the day. DISCUSSION An ENH RISK has been issued for S Turkey, extreme SE Mediteerranean, Cyprus and N Middle East with threat for severe winds, torrential rainfall and marginally large hail. Widespread forcing should continue from the ongoing overnight / morning storms as main trough and front will be pushed across Turkey towards ENE. Despite marginal instability, strong shear and helicity are favorable for supercell storms with mainly heavy rainfall, hail and wind
Large-scale weather cycles, such as the one related to the El Niño phenomenon, affect two-thirds of the world's cropland. In these so called climate oscillations, air pressure, sea level temperature or other similar factors fluctuate regularly in areas far apart in a way that causes rain and temperature patterns to shift significantly.
Saharan dust comes into parts of southern, eastern and southeastern Europe towards the end of the week!
A new cutoff low moves into the Mediterranean towards the end of week, pushing a new wave of Saharan dust into southern, southeastern and eastern Europe. Current model guidance suggests quite significant dust loads. After several waves of thick Saharan dust for southeastern Europe and eastern-central Mediterranean, a new wave pushes significantly more to the north and the west, affecting a much larger part of Europe. Latest model guidance indicates a wave of Saharan dust advecting with southwesterlies across the central Mediterranean / Tyrrhenian sea into the Adriatic region and western Balkans by late on Friday. The main dust concentration pushes into eastern Balkans and Ukraine on Saturday, while behind it a corridor of dust establishes across the central Mediterranean,
Calima is coming to Canary Islands over the next several days, blowing large amounts of Saharan dust into the region. Calima is a hot southerly, southeasterly or eastely wind in the Canary Islands region. It typically carries thick Saharan dust into the region. See dust maps below for the evolution of the event over the next several days. Maps: University of Athens SKIRON model.
VALID FOR 28-03-2018 A large trough with a deep cyclone moves across W Europe with a secondary low crossing N France and Benelux, while an associated cold front pushes east as well. Very cold maritime airmass will be advected behind the front across the E Atlantic. Some ridging is expected across most of the Mediterranean while another short-wave trough will affect the SE Mediterranean while deepening and moving towards Turkey. A surface low will form ahead of it. Elsewhere, a weak high pressure centered over NE Europe provides stable conditions. A MDT RISK area has been issued for SE Mediterranean into far SW Turkey with threat for severe winds, torrential rainfall, large hail and tornadoes. Rather impressive parameters are shaping
The weather pattern for Europe this week will be dominated by a large trough / cutoff low forming over the Atlantic today and tomorrow and moving across western into central Europe by the end of the week. The system brings very unstable and unsettled weather across the western and central Mediterranean region, the Iberian peninsula, the southern half of central Europe and the Balkans. We look at the details below. A progressive pattern establishes today, with a broad area of low pressure over the Atlantic pushing into western Europe over the next two or three days. It produces a number of troughs and cutoff lows pushing into central Europe and the Mediterranean; these systems will produce unsettled weather, with locally
Ecologists are checking to see if Hurricane Harvey's unprecedented floods gave a competitive boost to fire ants and crazy ants, two of southeast Texas' least favorite uninvited guests.
Dust activity that engulfed parts of Greece on Thursday and again today continues tomorrow. We take a look at where Sahran dust will be concentrated tomorrow. More Saharan dust is expected tomorrow over the central and eastern Mediterranean as well as over the southeastern Europe. A particularly dense cloud will extend from Libya towards Crete island and the southeastern Aegean, into western and northern Turkey, across the Black sea into SW Russia. Smaller dust concetrations all over the southeastern Europe, central Mediterranean (S Italy, Malta) and the far eastern Mediterranean, including Cyprus. Note also the buildup of Saharan dust off the W coast of Africa towards the Canary Islands – a Calima event is coming! Dust load across the Mediterranean
Half of Alberta's upland boreal forest is likely to disappear over the next century due to climate change, a new study shows. The upland forest will be replaced after wildfire by open woodland or grassland, according to research from biologists.
Saharan dust all over the eastern and central Mediterranean and Aegean region today – March 26, 2018
Large amounts of Saharan dust are suspended in the air all over the eastern and central Mediterranean and Aegean region today. We take a closer look. NASA Terra / MODIS satellite image of the Mediterranean. Local noon, March 26. NASA Terra / MODIS satellite image made near local noon today shows extensive Saharan dust clouds over the southern Mediterranean, central and eastern Mediterranean, as well as the eastern half of the Ionian sea and much of the Aegean region. Greece is getting the most of it, with a new cloud forming just south of Crete. Also major dust moving into the Marmara sea region and western Turkey. The eastern Mediterranean, including the southern coast of Turkey and Cyprus are under
The coming week looks like it will be a dynamic one. Spring is here. A very dynamic pattern is ahead for the southern half of Europe: deep troughs and cutoff lows will produce unstable weather. We take a look at the general pattern first and then some highlights. A very dynamic pattern is ahead this week for the southern half of Europe: beginning on Tuesday, a broad low pressure area begins establishing across the Atlantic and SW Europe. The area will spread eastward across central, northern and eastern Europe through the second half of the week. Several troughs and cutoff lows will be pushed from the west into the Mediterranean region and the southernmost parts of central and eastern Europe,
Major amounts of Saharan dust for Greece, southern Italy, Albania, FYR Macedonia, Serbia, Bulgaria, Romania and Turkey on Sunday and Monday – update
