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.

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 ...

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....)

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...

This time last year at #EGU I met Jim Wilczack and he invited me to join him and an excellent team on this perspective piece that we've had published today!
It's helping a little with my EGU FOMO :)

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

The latest paper led by Kieran (with a little help from me) where we compare the traditional regression-based techniques that I've used a lot over Europe, to more complex machine learning methods to model state-wise Indian demand.
Lots of open data available too!

Excited to be involved in one of these exciting UKRI funded projects. www.ukri.org/news/africa-...

More calls like this please! :) #capacitybuilding #climateresilience #energymeteorology

Africa-UK physics projects to drive collaboration and innovation

A major new initiative is now underway to advance scientific research, innovation, and economic development across sub-Saharan Africa.

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.

Hannah Bloomfield @hcbloomfield19.bsky.social · Feb 26

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.

Hannah Bloomfield @hcbloomfield19.bsky.social · Feb 26

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.

Hannah Bloomfield @hcbloomfield19.bsky.social · Feb 26

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.

Hannah Bloomfield @hcbloomfield19.bsky.social · Feb 26

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.

Hannah Bloomfield @hcbloomfield19.bsky.social · Feb 26

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.

Key points I'd like anyone to get from this are given in the thread below :)

Bittersweet proposal rejection this morning with the feedback:
'9/10 Outstanding: The application very strongly meets all the assessment criteria.'

What can you even do at this point except just submit again and hope you win the lottery? #rantover #needsomechocolate #someonegiveUKRImorecash

Wildfires aren’t a problem in the UK, right? Wrong. Not on the same scale as we are seeing in LA, but there are thousands of wildfires every year in the UK. In the heatwave of July 2022 wildfires broke out in London.

Our new paper explores the risks: doi.org/10.1002/cli2...

Great to host Dr Ji-Eun Byun from Glasgow university today for a project meeting and fascinating lunchtime seminar!
Now just to finish off the project :)

Hannah Bloomfield @hcbloomfield19.bsky.social · Jan 7

I didn't have a single meeting today, spent all day making plots, drinking tea and eating apple crumble...and just needed to shout it into the ether.
Sometimes science is still glorious! :)
