Faoi Rabhaidh Aimsire na hOifige Meitéareolaíochta

Tugann BBC Aimsir dhá chineál rabhaidh aimsire eisithe ag an Oifig Meitéareolaíochta: Rabhaidh agus Réamhrabhaidh.

Rabhaidh -eiseofar iad seo nuair a mheasfar go mbeidh drochaimsir ann faoi cheann 24 uair.

Réamhrabhaidh -eiseofar iad seo breis agus 24 uair roimh aimsir dhian.

Tá trí chatagóir teagmhais ann, mar atá, Dearg, Ómrach agus Buí - is é Dearg an ceann is measa.

Bíonn Rabhadh agus Réamhrabhadh den dath céanna chomh trom lena chéile ach táthar á thuar go dtiocfaidh siad ag amanna difriúla. Mar sin, is é an difear idir Rabhadh Dearg agus Réamhrabhadh Dearg ná an t-am is luaithe a thiocfadh leis tarlú.

Nuair a bhíonn rabhadh i bhfeidhm, is féidir faisnéis iomlán a fháil ag Rabhaidh Aimsire na hOifige Meitéareolaíochta

Wandering jet stream means changeable weather

As the last few schools closed their doors for the summer, the jet stream decided to head south for its holidays too. This fast-moving river of air high in the atmosphere is the driving force behind our weather. When it's to the north of the UK (a normal summer position) we get warm, settled conditions but when it dives south then the rain and gales are steered our way and temperatures fall. That's how the summer holidays started for many of us, with some unseasonably wet and windy weather. The outlook suggests the jet stream will continue its meanderings well into August so we can expect further unsettled spells, although there are hints of something a little quieter for the middle of the month.

Windy start, sunnier finish.

Low pressure dominates the weather right across the UK at the start of the week bringing largely cloudy skies and outbreaks of rain, this heavy and persistent for a time across northern areas. Unusually strong winds around the depression bring the threat of gales to some parts of Wales and southern England.

Winds swing round to the north as the low moves away, bringing in colder air which leads to some particularly chilly nights as winds fall light and skies clear during the middle of the week, although it feels warmer by day as sunshine amounts increase.

A weaker weather system brings an increasing chance of showery outbreaks of rain to northwestern areas later in the week, although warmer air should start to spread in as winds swing round to the southwest ahead of another developing area of low pressure.

Unsettled weather returns

The jet stream is likely to start steering some more low pressure systems our way during the week, bringing a spell of unsettled weather. Northwestern areas will be most prone to outbreaks of rain and unusually strong winds. Wet and breezy weather is likely to push further south at times, but there is a good chance that much of England and Wales will experience some warm and dry weather, especially during the early part of the week.

A summer break?

There are some signs that the weather could turn more friendly during the second part of August, but it's not a particularly strong signal so there is a large degree of uncertainty and certainly potential for occasional brief unsettled spells. Equally, any hotter weather is unlikely to last for more than a day or two. Overall, it's looking possible that this August could follow the example of last August in coming out cooler than average overall.

An tseachtain seo chugainn

Time's running out for summer as we head on through August - will there be a comeback?

Réamhaisnéisiú míosúil
Ní furasta an aimsir a thuar níos faide ná seachtain nó mar sin chun tosaigh, fiú don réamhaisnéiseoir is mó taithí. Déantar samhaltáin uimhriúla casta a fháil ón Oifig Meitéareolaíochta agus ón Lárionad Eorpach do Réamhaisnéisí Aimsire Meánraoin (ECMWF) agus déantar iad a rith a lán uaireanta don mhí (agus don séasúr) atá le theacht. Ar an dóigh sin, cruthaítear pictiúr den dóchúlacht go rachadh cineálacha éagsúla aimsire i bhfeidhm ar an RA.
