So #ICYMI #OnThisDay in 1974, and into the following day, was the #Tornado #SuperOutbreak This montage of images is on the @NWS pages at: weather.gov/iln/19740403 Image
I have the following image as a poster in my office for several reasons, which I will expound upon in subsequent tweets. Firstly it was produced by hand by Theodore ‘Ted’ Fujita, who developed the F-scale (later the EF-Scale based in wind intensity and damage. Image
What I really noticed in the key/legend on the map was how he was also looking at the type of structure where fatalities occurred, something that other scientists (@StephenMStrader) were looking at before I came along, but once you start, you can’t stop. I’m pretty much obsessed. Image
It’s important to know and think about how to ameliorate (including the extent to which this is possible). I have been studying #tornado #epidemiology (fatalities & causes) to look at broad patterns as well as what happens precisely to individuals. Not new as @hebrooks87 there b4 Image
But this gives us a baseline for understanding/considering the multiple social #vulnerabilities that contribute to #tornadofatalities and injuries (which we shouldn’t discount as many are life changing - this includes the psychological impact) + impact on employment opportunities ImageImage
I created the previous graph and the following greyed/highlighted versions show where people were when they died (as taken from @NWSSPC data). This helps us understand risk and potential safer behaviours that can help with public understanding too. ImageImageImageImage
I am lucky enough to be able to work at the social science/Geography interface with a team of brilliant people including @Wxmanms1, @tlyzawx, @kimklockow and others as part of the VORTEX-SE project. My research focus is on societal risk and vulnerability alongside others...
...where we are trying to gain insight on the potential gaps and working with others to close them. Currently I am working with @SeaGrant to understand citizen perspectives, risks, vulnerability alongside adaptation strategies taken in severe weather events...
We hope to them work alongside communities to bring them together to find solutions to #sheltering options, being aware of #nocturnaltornadoes and getting the right information from multiple sources. This is why #socialscience is key to unlocking new solutions to limit impacts.
You can find out more about this work at a recent presentation I gave of our @NOAANSSL &
@MSALSeaGrant
project: 'Community Centered Co-Produced Knowledge & #Learning Towards #SevereWeather #Preparedness & #Resilience' to
@SESVRSymposium
...The map near the top of this thread is printed out A0 size on my wall in my office as a constant reminder of the complexities and potential solutions in reducing fatalities and injuries when #tornadoes occur. To find out more about the 1974 event see: weather.gov/iln/19740403

Second half of my #tornado safety & #preparedness for children & #families is now available. I expanded on learning from the previous comic strip & included some bi-lingual moments (65+m speak #Spanish at home in USA). 🙏 @AmericaGaviria for translations share.pixton.com/qe300ri
I wanted the comic to be whimsical and fun to read whilst addressing some of the issues around conversations with kids on safety and preparedness in severe weather events. #wxtwitter
Thinking about family members that may have grown up in another country with an absence of certain hazards (e.g., tornadoes) is important. Talking with them is a greta first step...

Something I have been working on: A #comic strip on #tornado safety for children and #families. We used this as part of a Mississippi-Alabama Sea Grant collaboration where we are returning VORTEX-USA research back to the community. Last week with 1st grade share.pixton.com/qeuyvug
I'm adding here in the right order and to show the way in which the #comic strips were designed to be viewed by the reader! Communication is crucial for #wxtwitter professionals...
This one has me in the comic strip as the communicator of #tornado warning signs and safety precautions...we developed the graphic in the fifth frame in house at @NOAANSSL as part of a project in Mississippi and Alabama...

What is a ‘#stingjet’? The jets get their name from their resemblance to the sting in a scorpion’s tail, spotted as they develop on satellite images, where the end of the so-called cold conveyor is marked by a hook-shaped cloud with a point at the end.
theguardian.com/uk-news/2022/f…
A strong jet stream can generate a new storm every day or two as
a narrow, focused region of extremely strong winds embedded within the larger area of strong winds and lasting just a few hours, potentially in #StormEunice #stingjet #wxtwitter.
Satellite analysis of post-tropical storm Ophelia on October 16, 2017. Note the branches of “banded cloud head” pushed towards the SW Ireland, indicating that the #stingjet structure is likely developed. Source: EUMETSAT

THREAD: Individuals with access and functional needs (#AFN), such as adults with #disabilities, may have additional needs that must be considered in planning for, responding to, and recovering from a #disaster or public health emergency. This guide from: phe.gov/emergency/even…
C = #Communication
Individuals with communication needs may speak American Sign Language (#ASL), have limited English proficiency (#LEP), use braille print or use other auxiliary aids and devices to communicate or navigate their environment...
C = #Communication (continued)...These individuals may have limited ability to hear announcements, see signs, understand messages, or verbalize their concerns. Planning for these needs ahead of a #disaster or emergency is crucial.

THREAD: Some interesting uses of the @TwitterAPI to explore #extremeweather events in relation to #climatechange. I found the cognitive dissonance explored in the #wildfires in Australia to hold up based on…developer.twitter.com/en/use-cases/b…
…research that has been carried out. This is where #socialscience can be a leader in engaging with the public. Work that I’m doing now creates spaces for conversations that explore #severeweather risk, focusing on issues of shelter access for those without a range of resources
…we help #communities explore their options, including building consensus on alternative shelter provision, especially where funding is an issue in rural communities. We work with faith groups who have strong #trust and social networks alongside other stakeholders to explore…

Today is International Day of #Disaster Risk Reduction. A recent report found investment uneven/poorly directed “Every US$100 spent on disaster-related development aid, only 50 cents are invested in protecting development from the impact of disasters” #DRR undrr.org/news/covid-19-…
The bulk of the spending, US119.8 billion was earmarked for emergency/ #disaster response and US$7.7 billion was spent on reconstruction, relief, and rehabilitation. This is the wrong way around. It is short-sighted and undermines climate change adaption by poorer countries.
The lack of foresight and investment has been directly seen in the impact of #COVID, as well as its response. Investment and actions taken sooner, based on the assessment and advice of experts and based on modeling and exercises (such as Cygnus in the UK) should have been enacted
