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.

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.

Cold conveyor belt brings cold, moist air towards the center of the cyclone, bringing precipitation. The dry intrusion brings cool, dry air into the cyclone. As the precipitation from the cold conveyor belt falls into the dry air of the dry intrusion, evaporative cooling occurs.
This occurs at altitudes up to about 3-4 km. The cooled air is denser than the surrounding air & descends rapidly to the surface, producing even stronger winds within the intense wind field of the cyclone. The entire region of cooled, accelerated air is narrow, forms a #stingjet.

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

🧵 #ida #HurricaneIda with power out safe #generator use is incredibly important! Some rules:

Never use a #generator, grill, camp stove or other gasoline, propane, natural gas or charcoal-burning devices inside a home, garage, basement, crawlspace or any partially enclosed area.
Keep these devices outdoors, away from doors, windows and vents that could allow #carbonmonoxide (CO) to come indoors.
Opening doors and windows or using fans will not prevent CO buildup in the home. Although CO can't be seen or smelled, it can rapidly lead to full incapacitation and death.

THREAD: I have been trying to track down EVERY #Mississippipi public #StormShelter using publicly available info. Using @googlemaps I have completed about 2/3 so far. I checked out every shelter, confirmed by crosschecking satellite w/ Streetview data...google.com/maps/d/edit?mi…
...I then screen grabbed the exact position from the road and produced a @googledocs document which contains corrected or updated locations. I sometimes had to use @googlemaps Street view) to hunt down the ACTUAL locations of #stormshelters for #tornado: drive.google.com/file/d/1lnRN9J…
Then I used Streetview to Green grab the locations and add to my map that I am making available publicly. I hope this helps folks learn and know where there are or there are not shelters nearby. If there are not, what options are available to you. Certainly a convo worth having..

This is #SantaBarbara, California. It really is a beautiful place to live, but expensive too. (Secretly - or maybe not - I would LOVE to live and work here). It is also where I carried out my #PhD fieldwork, Living my best #phdlife...
Like many places in Southern California, there are a number of #naturalhazards that can and do impact on the city and its surrounding County:
