for a while. The reason it’s not shifting is because of the position of the jet stream, which is driving south through the Atlantic and creating a trough, allowing this low to mill around and driving up other weather fronts.  “Fast forward to Monday and the pressure hasn’t really changed very much

dramatically in extent over time and you may not always find a station very close to the location you want to know about. The number of elements recorded and the regularity of observations also varies greatly between stations and also can vary over the life of an individual site. Regular observations

Meteorologist, Laura Paterson, said: “It will feel very cold this weekend, with strong winds bringing heavy showers to many parts.  Northern facing coastal areas will see the most frequent showers, whilst elsewhere will see more in the way of sunshine. These showers could contain hail, and turn to snow

forecasting which can cause errors in the forecast, including: the starting conditions the forecast model The starting conditions The future evolution of the atmosphere is very sensitive to small errors in the analysis that we use to start the forecast. To start an ensemble forecast we first make

Currently in the UK, most locations receive a number of ice days each year, but if we do not curb greenhouse gas emissions, these days could become very rare in southern England in the 2040s, and although they are still expected to occur further north – especially in upland areas – the frequency

are presented to help understand the spatial patterns across the entire province. The analysis shows that there is likely to be a significant warming trend throughout the twenty-first century. It also suggests that people in Ontario are very likely to suffer a change greater than 28C to mean

scenarios, and future warming are all frequently discussed This can get very confusing, particularly as two or even three of these approaches might be referred to in the same article. There is also significant overlap between these ways of discussing climate change, which can add to the confusion

and next week might have in store. A winter of contrasting hazards Snow has already played a prominent role this January, with northern Scotland seeing prolonged disruption before conditions finally began to thaw. As that thaw took place, Storm Goretti swept in, bringing very different hazards

that takes the laws of physics that are fairly well understood and applies them at scale to observations of the current state of the atmosphere. To do that is very, very computationally expensive. It’s simulating the future state of the atmosphere. Operationally, that’s 200 to 300 terabytes

• Define the ground system requirements • Develop Cost Estimate Issues • Reviews need to be coordinated and not duplicated. • Define Environmental Requirements (Vibration Loads, EMC, Contamination, etc) • Long phase A to define & reduce risks has been very beneficial
