Meteor photography 101

Severe Weather Europe - 21. Oktoober 2017 - 21:41
Photographing meteors – like the Orionids, active right now – is loads of fun and with a bit of luck, you can catch a big, bright one! Here is how you do it. Equipment: A camera with the option of making long exposures. Any interchangeable lens camera (DSLR or mirrorless) will have the option, many compact cameras and some phone cameras also have the option. A remote trigger for the camera (or timer). A tripod. A meteor shower. The stronger, the better. How to do it – camera settings The best time to photograph meteors is during maxima of major meteor showers, such as the Quadrantids, Perseids and Geminids. Moderately strong meteor showers, such as the Lyrids, Southern Delta Aquarids,

Windstorm Brian hits Ireland & the UK – update

Severe Weather Europe - 21. Oktoober 2017 - 11:03
Cyclone Brian has reached Ireland and the United Kingdom: peak winds up to 110-130 km/h are being reported. Details below. Current situation Brian’s center is currently located over central Ireland, at central pressure of 976 mbar, significantly up from yesterday’s values below 970 mbar. Peak reported winds are in 110-130 km/h range: Bouee 62107 (SW of Cornwall, UK) – 126 km/h, Sherkin Island (Ireland) – 112 km/h, Shannon Airport (Ireland) – 101 km/h, Mumbles (UK) – 108 km/h, Pembrey Sands UK) – 104 km/h.

US ocean observation critical to understanding climate change, but lacks long-term national planning

ScienceDaily - 20. Oktoober 2017 - 19:57
Ocean observing systems are important as they provide information essential for monitoring and forecasting changes in Earth's climate on timescales ranging from days to centuries. A new report finds that continuity of ocean observations is vital to gain an accurate understanding of the climate, and calls for a decadal, national plan that is adequately resourced and implemented to ensure critical ocean information is available to understand and predict future changes.

The Orionid meteor shower peaks this weekend!

Severe Weather Europe - 20. Oktoober 2017 - 13:51
Meteor showers are great fun! The Orionid meteor shower peaks this weekend. Here are some tips on how to see it best! Orionids are bits and pieces of the well-know comet Halley. As the comet rounds the Sun every 76 years, it releases a stream of small dust particles in its path. The Earth ploughs through the stream every year around October 20-23. The Earth and particles collide at 67 km/s and the particles burn up high in the atmosphere, producing bright streaks of light – meteors. The dust particles (called meteoroids) travel on parallel paths, but due to the same geometric effect that makes it look like two railway tracks merge in the distance, all Orionids will seem to

Update on approaching storm Brian: windy weather ahead for Ireland and parts of UK

Severe Weather Europe - 20. Oktoober 2017 - 10:39
Update on approaching Cyclone Brian. Cyclone ‘Brian’ is still far from land over the Atlantic ocean west of Ireland and it has now deepened to 965 mbar. Winds are likely gusting at up to 150-160 km/h. The system is approaching Ireland and will begin affecting it by early evening. However, as the system will likely be gradually weakening, the peak gusts tonight will probably reach ‘only’ up to 100 km/h (in S Ireland) and peak tomorrow morning at 110-120 km/h. Windy weather ahead for Ireland and the UK, some damage potential. ARPEGE model guidance for peak wind gusts today and tomorrow. Maps: Wxcharts.eu.

Windstorm Brian to affect Ireland and parts of UK with storm force winds

Severe Weather Europe - 19. Oktoober 2017 - 22:12
The system is still on track to affect Ireland and parts of the United Kingdom late tomorrow and on Sunday. Current model guidance suggest peak winds of 110-130 km/h in southern Ireland and lesser winds elsewhere. Currently the system is deepening over the central northern Atlantic, having dropped by 9 mbar in the past 6 hour (bombogenesis!) to current central mean sea level pressure of 979 mbar. The system is tracking ENE towards Ireland. Morphology of the storm in satellite imagery indicates a possible sting jet forming, although satellite imagery along is insufficient to ascertain its presence or absence. Recall that cyclone Ophelia likely developed a sting jet just before landfall, causing 191 km/h peak wind gusts just off the

Up to 100 mm of rainfall, locally more, is indicated by high-res models for extreme NE Spain and S France by early tomorrow morning. Expect local flooding. Follow ongoing storms on radar: Spain France A cutoff cold core upper low is forming over the Iberian peninsula, with thunderstorms ongoing along the cold front in the eastern part of the peninsula and extreme western Mediterranean. Favourable south-north storm motion in extreme northeastern Spain and southern France will result in accumulation of rainfall from successive storms, locally up to 100 mm or more. Expect local flooding. Moderate instability with up to about 1000 J/kg MLCAPE overlaps favourable with strong 30-50 kt deep-layer shear.

A windy day is ahead for extreme southwestern UK, the English Channel and northwestern France, with gale force winds gusting up to 90-110 km/h. Another, stronger windstorm is coming tomorrow! A small cyclone rapidly forms from a short wave trough over the Atlantic and deepens south of Ireland, moving eastwards into the English Channel.

New windstorm heading for Ireland and UK on Friday and Saturday

Severe Weather Europe - 18. Oktoober 2017 - 21:44
Models are still on track for a significant windstorm over Ireland and the United Kingdom on Friday and Saturday. GFS model guidance for mean sea level pressure and peak wind gusts late Friday/early Saturday. Map: TropicalTidbits.com. Both GFS and ECMWF are still in good agreement for the arrival of a deep cyclone towards Ireland and UK. While the exact track and intensity is still fairly uncertain so far ahead, both models indicate a deep cyclone with central mean sea level pressure down to 960 – 975 mbar. Current GFS model guidance indicates a very deep cyclone with central pressure approaching 960 mbar or even below that mark, and peak wind gusts of 120-130 km/h around landfall. Map: Wxcharts.eu.

Finally some much needed rainfall for part of Iberia today, Oct 18th

Severe Weather Europe - 18. Oktoober 2017 - 10:19
Models are in agreement for some good amount of rain across Portugal and especially Spain today as a rather large upper low crosses the Iberian peninsula from W to E into western Mediterranean. Locally 50-80mm will be possible through the next 24 hours, more likely across S and NE Spain. In moderate shear and instability, some severe weather will also be possible where storms will be capable of producing strong winds, torrential rainfall and marginally large hail.

A new intense windstorm possible for UK and Ireland later this week – GFS and ECMWF models in good agreement on new tropical development

Severe Weather Europe - 17. Oktoober 2017 - 16:01
GFS and ECMWF model guidance are currently in good agreement on the new tropical depression that may affect the British Isles and Ireland. Invest 92L, as the depression is currently designated, may strengthen into a strong storm to hurricane force cyclone as it crosses the Atlantic and approaches Ireland and UK. GFS model guidance for mean sea level pressure and peak wind gusts late Friday/early Saturday. Map: TropicalTidbits.com. At this time, GFS model guidance indicates a very deep cyclone with central pressure approaching 960 mbar and peak wind gusts of 120-130 km/h around potential landfall. ECMWF indicates an only slightly weaker system at 970 mbar central pressure. Comparison between GFS and ECMWF model guidance in mean sea level pressure. Maps:

What everyone in the region is seeing is the thick smoke from massive fires in northern Spain and Portugal, which nearly blocked out the Sun in western France and the United Kingdom yesterday. The northeasterly flow pushed the smoke over northern central Europe by this morning.

New tropical development may produce a new intense windstorm for UK and Ireland later this week

Severe Weather Europe - 17. Oktoober 2017 - 8:11
Interestingly, latest GFS model guidance indicates development of a new tropical depression that may affect the British Isles and Ireland. The system, designated Invest 92L is currently located east of the Bahamas and will track ENE-wards towards across the Atlantic in the next 72-96 hours. Current model guidance suggests the system could produce strong storm to hurricane winds in the vicinity of Ireland towards the end of the week. While it is too early for detailed forecasts and future model runs may change significantly, the system definitely warrants monitoring. We will be providing further updates.
