1. Odd one outAll but one of these measure the weather. What do they do? Can you spot the odd one out?
2. The answer is…None of them.

4. Odd one outWhat’s a weather banana?Similar to a ‘weather stone’ or a ‘weather stick’, a weather banana can be used to indicate local conditions. Suspended on a string…If it is wet, it is rainingIf it is swinging, it is windyIf it casts a shadow, it is sunnyIf it is blurry, it is foggyIf it is white, it is snowingIf it is covered in ice, it is frostyIf it is missing, there has been a tornadoIf it is hanging sideways and swinging wildly, and is wet, and looks a bit bruised, there is a tropical cyclone
5. How not to lose a Tropical cycloneTropical Cyclones
6. Lost at sea?How not to lose a tropical cycloneThe Earth is big. The Pacific Ocean, for instance, is over 100,000x bigger than London, or nearly 670x bigger than the whole of the UK.Even something like a 1000 mile-wide tropical cyclone can be hard to find.So how to we keep track of where they are?Really big. Huge, in fact.
7. Data. Lots of data.DataData collectionAlgorithm run on supercomputer creates forecastsMeteorologists study forecasts and create maps and information for the public based on what looks most likely to happen.
8. Lets look at data collection…DataData collectionThe more data we have, the more accurate our weather forecast will be, but the more complex our model and the longer it will take to run on a supercomputer.We get lots of different types of data from lots of different sources. To track tropical cyclones we especially use a few sources…
9. When they are in the middle of oceansWeather satellites provide regular information about cloud, winds, precipitation, and temperature over the whole planet.
10. We also get a lot of data that is routinely collected by ships and planes during their normal day.There are a lot of ships and planes moving around at any moment! This provides lots of data, though not in the middle of a storm (which everyone tries to avoid).What other regions are not visited by ships and planes?Planes - https://vimeo.com/88093956Ships - https://vimeo.com/47077342
11. When tropical cyclones get a bit closer to land we can fly out to them and take direct measurements. Commercial flights avoid hurricanes, but one plane flies directly into and through the storm.Hurricane Hunters: Flying through a hurricane eye-wallhttps://www.youtube.com/watch?v=a-SnxC-BkPoWhile they are in there they drop several ‘Dropsondes’ – weather instruments that parachute down to the ocean (and are lost forever) taking measurements of the storm as they go and transmitting the data outDropsondehttps://www.youtube.com/watch?v=L2TQgXzvkDkWhen they are far out to sea…
12. As they cross land…Weather (doppler) radar
13. DME taskYou are a Japanese meteorologistA tropical disturbance has been detected.Initial forecasts suggest a tropical cyclone – a Typhoon – may form, and could make landfall in Japan.You need to keep track of it and provide data to the supercomputer and forecasters.
