Storm Cloud: Changes with the Weather

Product Information

For the past year, weather forecasting has been going through a revolution as models such as GraphCast, Huawei’s Pangu-Weather and Nvidia’s FourcastNet have made meteorologists rethink the role AI can play in weather forecasting. GraphCast improves on the performance of other competing models, such as Pangu-Weather, and is able to predict more weather variables, says Lam. The ECMWF is already using it. With this decorative weather predictor, you’ll never get caught in the rain again because it will tell you right before it happens. Does it sound like magic? Not really. This instrument is actually based on a classic device called ‘storm glass’ which was popularized by Admiral Robert FitzRoy. During his voyage with Charles Darwin aboard the HMS Beagle in 1831, FitzRoy claimed that the device helped him forecast the weather with accuracy. Despite FitzRoy’s endorsement, storm glasses fell out of favor when cheaper mercury barometers were introduced in the 19th century. This explains why many people do not even know that this instrument ever existed. This is a huge topic, so let me know what questions you still have about clouds & weather prediction. Most importantly, have fun out there! Cumulonimbus clouds also have the greatest vertical depth of any cloud and frequently extend all the way through the lower, middle & even upper levels of the sky in a single cloud. How To Predict Rain With The Clouds These same tests also showed to be no better than a 50/50 chance of being correct, essentially leaving the predictions up to chance. Our opinion is that storm glasses should not be relied upon as a legitimate weather instrument but more of a conversation piece for your office or coffee table.

If there are large flakes throughout the liquid, it will be overcast in temperate seasons or snowy in the winter. These clouds drop a large amount of precipitation in a very short period of time, but the overall rain event typically lasts for much less time than nimbostratus rain. The researchers will then incorporate their new AI model into the Met Office’s existing supercomputer infrastructure to be able to more routinely compare its accuracy to their existing physics-based forecasting methods already in use.If you want to know whether cirrus clouds are a sign of storms ahead, look for signs of increasing instability on the middle and lower cloud levels over the next 24-48 hours.

In the first phase of the project, researchers will develop a new AI model, known as a graph neural network, to forecast weather patterns. This will allow them to test the accuracy of their new model against existing weather forecasting methods – so called numerical weather prediction. Next, altostratus clouds start moving in. These will emerge from the same general direction of the sky as the cirrus clouds. Altocumulus clouds are just like cumulus clouds except they happen at a higher altitude of the sky.

Of course, there’s a lot more we could say about predicting weather with clouds, but I hope this article has inspired you to get outside and start watching the sky with a more critical eye. Learn to identify the difference between cumulus and stratus clouds at low, medium, and high levels of altitude.

In the UK a storm will be named when it has the potential to cause disruption or damage which could result in an amber or red warning. This is based on our National Severe Weather Warnings service, which is a combination of both the impact the weather may have, and the likelihood of those impacts occurring. This is very different from the other main type of cloud that produces rain. 7. Cumulonimbus Clouds This is a very small cumulonimbus cloud. Notice the cloud extends upwards with great vertical depth, with rain falling to the ground underneath.The various states of the liquid and the predicted weather conditions associated with them (as shown in the diagram above), are the conclusions of Admiral FitzRoy. It has not been substantiated by any recent research or studies.
