🧩 The paper ends by exploring the causes of wind/solar variability across the whole of Africa. A great resource for those wishing to dig into the drivers in more detail for early warning systems.

☁Rajeev's then developed a unique set of weather patterns that explain causes of year-to-year variability over Africa that are more bespoke to variability than the traditional ENSO/MJO style teleconnections

⚖ This helps us to understand the impacts of large scale modes of variability on potential wind/solar sites while still thinking about important logistical constraints.

Alongside @hcbloomfield19.bsky.social, we've written an insight as to why the insurance industry is impacted by, and requires an understanding of, weather and climate.

Yeah it baffles me how much of my money the trains take compared to the cost of my commute if I drove :(
Maybe I need to get into cycling up the A1...

Return train London --> Brussels for only £70 and 2 hours each way. Cheaper than the equivalent flight, and less faff at each end.
The clean travel revolution is happening! 🙌

(Let's not mention my Leeds --> London train is more £ than the whole rest put together....)

Balancing Informativity and Predictability in Circulation Type Forecasts: A Case Study of Energy Demand in Great Britain Circulation types can be a powerful tool for assimilating meteorological information into applications, such as forecasts of energy demand. However, there are usually many different circulation type ...

With all of these different weather regimes/patterns/teleconnections/TCTs* how do you decide which ones to use to predict at different lead times?

Well we've had a go at finding you the answer!

Nice work led by Kristian.

*my personal favourite! :)

One of my favourite interactions with the peer review system came up as a Google memory today 😂

My wonderful University have just completed the paperwork on a grant I had that ran from Oct 2023 - Mar 2025. And they're confused why I'm not particularly interested... It's been FINISHED two months 😂🤦‍♀️
Makes me feel less bad about that fence i've been meaning to paint for 2 years in my garden...

Wind and solar energy droughts: Potential impacts on energy system dynamics and research needs This Perspective article provides a brief overview of the topic of wind and solar energy droughts (henceforth WSDs). It does not attempt to provide a complete l

Our rapidly changing climate means it is of key importance that climate scientists continue to work with energy system modellers to develop best practices for stress testing highly weather-sensitive future power systems and this report continues to make progress towards this goal.

Using the UK Met Office's UK Climate Projections (UKCP18) We can see the anticipated changes in energy system composition have a much larger impact on management of the future energy system than near-term climate change.

We also modelled 28 European countries for the present day climate, and can see that while GB is experiencing its most extreme short-duration stress events, it is common for interconnected countries to also be experiencing times of high need.

Overall, the amount of non-renewable energy the system needs to find (the difference between demand and renewable generation) will decrease in future power systems, given the expected expansion of renewables capacity. But they're not generating consistently through the year, so balancing is needed.

The energy system will become more weather-sensitive over time, due to the electrification of the economy and the rapid increases in wind and solar generation. Despite this, there will likely remain periods of low renewables generation, which will require low-carbon flexibility solutions to manage.

We had three types of challenging event, a short-duration stress event (a few days of high demand and low renewables, driven by a low wind cold snap) a challenging year (where generally demand is higher and renewable generation is lower, and a multi-year challenge.

In this project I used time series of demand, wind and solar power for now, mid-2030s and 2050 to think about weather-driven stress on power systems for a present climate and for some future warming scenarios.

An absolute pleasure to work with the Climate Change Committee on this piece of work out today:

Reasonable worst case stress test scenarios for the UK energy sector.
