Join Hugo and Bogdan to find out more about weather balloons. What are they? What do they measure?

Watch a short video of a balloon launch from Capel Dewi (Wales) here

Since today we are not launching weather balloons for the NAWDEX project, Hugo had some time to test other meteorological instruments installed at Capel Dewi. Today we are briefly introduce the SODAR (SOnic Detection and Ranging).

Today's episode focusses on the science behind the NAWDEX project as explained by special guest Prof. Geraint Vaughan from the National Centre for Atmospheric Science (NCAS).

Welcome to our first of hopefully daily updates on a project called NAWDEX, in which Hugo and Bogdan will be describing the day-to-day life during a field project. We aim to post daily updates on the science and practical aspects of field work.

NAWDEX (North Atlantic Waveguide and Downstream Impact Experiment) is an international project looking at the jet stream. One of it's aims to understand how diabatic processes (ie. heating and cooling) within clouds and how they affect the structure of the jet stream.

Today we will briefly introduce the project and who is taking part. Tomorrow we'll tell you about our first weather balloon launches. Please feel free to contact us, if you have any questions about the project or just weather in general.

Hurricane Bertha is no more but she may or may not be heading for the UK this weekend. Join the Will, Sam H and Tim on the Barometer Podcast to find out about her journey, why such weather systems are difficult to forecast and the chances of bad weather at the weekend.

The podcast was recorded on Thursday 7th August, 2014. Check the Met Office website for updated forecasts and weather warnings here.

Join Hugo, Richard and Geraint on a tropical island adventure where we discover the importance of ozone near the equator. We discuss how ozone is transported though the atmosphere and ask the question: "How do the towering storm clouds in the tropics affect the composition of the atmosphere?" We travelled halfway across the globe to Papua New Guinea with our weather balloons to gather the data that we needed to find out.

This was recorded in February 2014 during the Co-ordinated Airborne Studies in the Tropics (CAST) campaign.

Join Will, Eoghan and Sam as they discuss the impending football World Cup and what the weather in Brazil might have instore for the teams and fans. Managers,players and fans alike will be searching for a scapegoat for their forthcomingfailure and the weather is likely to play a role.

Is there even a chance of snow at the World Cup?

Will and Sam are joined by Roz Pidcock from Carbon Brief to chat about communicating science and the recent Intergovernmental Panel on Climate Change (IPCC) reports, which have featured heavily at EGU 2014. Find out about the wide range of sessions relating to climate science that took place this week.

Also, stay tuned at the end for a special message.
You can find Roz's blog posts about the science on offer at EGU 2014 below:

Will and Sam catch up with Andreas Petzold from Forschungszentrum Jülich in Germany to talk about a program called IAGOS, which puts instruments on-board commercial aircraft to do routine measurements of the atmosphere. Join us to find out the benefits of such research and the important insights that we have gained from it.

Sam catches up with Jane Robb, the Educational fellow for the EGU, to talk about all of the wonderful educational initiatives that EGU currently run, including the Geosciences Information for Teachers (GIFT) Workshops and the “I’m a Geoscientist get me out of here” project. Jane also provides some top tips to all scientists that want to communicate their research to a school audience. 

Sam and Jane also talk briefly about the gamification of crowdsourcing and citizen science, in order to encourage members of the public involved with helping scientists to carry out their research. The game that Sam mentions is called Cropland Capture, and it is well worth a gander!
