A new, very intense super typhoon Trami has developed in the western Pacific this weekend. It has already reached a CAT 4 strength today. Trami packs sustained winds of 140 mph and central pressure of around 938 mbar. The future track of Trami will lead it towards Taiwan and then it will turn north towards a potentially devastating landfall in Japan. Latest infrared satellite imagery reveal an impressive structure of this super typhoon, with tiny pinhole eye surrounded by an compact intense eyewall and a textbook almost undisturbed upper level outflow. Trami will be moving into favorable sea waters for additional strengthening through the next 72 hours, so an intensification into a monster CAT 5 super typhoon is expected later […]

Jahe ja tavapärane sügisilmaga nädal, kuhu jagub tuult, vihma ja ehk ka öökülmi.

Paavsti missa ajal keskpäeval vaid 10 kraadi (lähemalt https://ilm.ee/?517339).  /---/ Räägitakse märjast lumest – jah, hingemattev soojus on läbi ja leppida tuleb tavalise sügisilmaga. Märga lund vast ei tule, aga lume- või jääkruupe küll, miks mitte. Talvemärkideks on siiski vast veel vara.Nädal lõppes madalrõhkkonna edelaserv, mis tõi mitmele poole hoovihma, kohati rahet ja äikest, kuid öösel määrab ilma selle lõunaserv.

Nädala algul aktiivsed tsüklonid eemalduvad meist, kuid vaatamata sellele on ilm tuuline ja esineb sajuhooge, prognoosib ilmateenistus.

An Arctic outbreak is evolving across Europe today, starting to develop across the NW Europe this afternoon. An associated sharp and intense cold front will rapidly move towards east-central Europe, across Balkan Peninsula and Mediteranean through the next 3 days. Much colder weather will spread across eastern half of the continent, while west/southwest Europe remains under strong ridge and heat wave. Monday, Sept 24th, 00 UTC A deep trough will be pushed into east-central Europe tonight, with an associated surface low over south Poland. An associated coold front is expected to bring severe line of storms across parts of central Europe later this afternoon, evening and tonight. A very intense, hurricane force winds will be associated with the front crossing […]

The sharp and intense cold front that is crossing central Europe today will bring an intense, locally hurricane-force windstorm into northern and eastern Alps tonight and tomorrow morning. The sharp and intense cold front, which is expected to cause significant severe weather in central Europe today, will graze the northern and eastern Alps tonight. Wind gusts at higher elevations in the Alps will surpass 150-170 km/h and likely approach and locally exceed 200 km/h. In fact, latest ICON-EU model guidance indicates peak gusts of 220-240 km/h! The windstorm will persist from early evening on Sunday until mid-morning on Monday. Peak wind gusts across the Alps from Sunday evening to Monday morning, ICON-EU model guidance. Maps: Wxcharts.eu

The upcoming sharp cold front passage will produce severe Tramontana and Bora winds in the Adriatic region. Marginally severe Tramontana winds are expected tomorrow morning over the northern Adriatic region, followed by severe Bora winds through the rest of Monday and much of Tuesday. Tramontana is a short-lived, transient, but often intense northerly wind blasting from the Alps across the plains of northeastern Italy between Venice and Trieste, across the northern Adriatic, also affecting western Slovenia and Istra in NW Croatia. Typically Tramontana winds reach 80-100 km/h, but have reached up to 200 km/h. Bora, also known as Burja in Slovenia and Bura in Croatia, is a frequently intense downslope (catabatic) northeasterly wind, developing along the eastern coast of the […]

23. septembrini on Eesti Loodusmuuseumi hoovis avatud igasügisene seenenäitus. 56. korda toimuval väljapanekul on eksponeeritud nii söödavad, mittesöödavad, tinglikult söödavad kui mürgised seeneliigid ning tähelepanu all on ka tänavune aasta seen tuletael.

Augusti keskel alanud Tartu linna ja lähiümbruse elanike liikumisviiside uuringule saab veel vastata kuni 23. septembrini k.a. Igal nädal loositakse uuringus osalejate vahel välja auhindu.

MTÜ Raamat Rahvale kutsub Sind taas 23. septembril kell 11.00 - 15.00 Kultuurikatlasse toredale perepäevale, kust võid tasuta koju viia täpselt nii palju raamatuid, kui kanda jaksad!

Astronoomiliselt algab sügis pühapäeva ööse kell 04.54 ehk pühapäeval ärgates oleme juba sügiseses ajas.

Kätte on jõudnud võrdpäevsuse aeg, aga täna pole öö veel päevast pikem. Kuid pööripäeva järgselt saabub õhtune pimedus varsti peale päikeseloojakut. Juba tunni möödudes võime selge ilma korral näha taevas tähti, seda seal, kus valgusreostus napim.

Tegu on äärmiselt kummalise aastaga. Fenoloogilise sügise alguseks  peetakse vahtralehtede värvumise algust (pikaajaliste vaatluste põhjal 11.septembril).

VALID FOR 23-09-2018 SYNOPSIS The pattern evolving across Europe tomorrow is characterized by a strong ridge over eastern Atlantic and SW Europe, while a deep trough is being pushed from north towards the east-central Europe.
