Sylvia’s solution

In this video Sylvia demonstrates the solutions to this Week’s practical activity; the isoline drawing exercise in Step 3.11. We have also provided the solutions for the exercise on a …

Weather forecast game

This week is your last chance to submit your prediction in the weather forecasting game, or to see if you can improve on your score from the previous week. If …

Rotating fluid dynamics

Now that you have seen the demonstration of the Coriolis effect in Week 1, let’s look at how this tank of water represents the atmosphere rotating with the earth. Pete …

Drawing isolines

In this activity you’ll put into practice some of the knowledge you have learnt so far. You’ll be drawing various isolines on the maps we’ve provided, which will further help …

Guide to weather symbols

The above is a typical simplified weather symbol from a chart of weather observations. Let’s look at some other symbols which you may come across when looking at weather reports. …

The effect of people

Carbon Dioxide (C02) concentrations in the atmosphere, increased by over 40% from 278 ppm (parts per million) in 1750 to 400 ppm in 2015. Figure 1: The diagram above shows …

Changes over time

Let’s look at the Sun first, and specifically the orbit of the Earth around the Sun. There are three ways in which the Earth’s orbit changes over time, known as …

The atmosphere

The diagram in Figure 1 provides an illustration of the Earth’s Radiation budget. It shows the various ways energy or radiation can move through the climate system . Incoming solar …

The leaky bucket

How are the flow of energy we get from the Sun and the flow of energy the Earth loses to space, related to each other? A useful analogy is a …

The Sun and the Earth

What determines the climate of the Earth? Ultimately, the Sun, our nearest star. Solar energy is absorbed by the Earth’s surface, warming it and driving the weather patterns and therefore …

Introduction to anticyclones

So far, we have been looking at low pressure systems; cyclones. But what about high pressure systems; anticyclones? From a weather perspective anticyclones can be quite boring. Where the air …

Sylvia’s solution

How did you get on? In this video, Sylvia demonstrates the solution to the air mass exercise in the previous Step. You may have noticed the ‘geostrophic wind scale’ in …

Weather forecast game

We’d like you to have a go at trying to predict the weather in Reading, in our game hosted on the Royal Meteorological Society website. We’ve included a link to …
