Hurricanes, tornadoes and sea level rise

 Further to our explorations in AI here and to the previous post here, this is a 'conversation' with Copilot, Microsoft Bing's AI extension. Conversation means that you can daisy-chain questions without repeating them, either to extend or to zero in:


Q: Difference between hurricane and tornadoe

https://en.wikipedia.org/wiki/Tornado

A: Hurricanes and tornadoes are both powerful weather phenomena, but they have some key differences:

Formation and Location

- Hurricanes form over warm ocean waters, typically near the equator. They require a pre-existing weather disturbance, warm tropical oceans, moisture, and relatively light winds¹.

- Tornadoes form over land, usually from severe thunderstorms. They often occur in areas with high wind shear, where there is a significant change in wind speed and direction with height².

Size and Duration

- Hurricanes are much larger, with diameters ranging from 100 to 2,000 kilometers (up to 1,000 miles). They can last from several days to a few weeks².

- Tornadoes are smaller, typically less than 2 miles wide, and usually last only a few minutes to a couple of hours².

Wind Speed

- Hurricanes generally have wind speeds less than 180 mph².

- Tornadoes can have wind speeds up to 300 mph, making them more intense in terms of wind speed over a smaller area².

Impact and Damage

- Hurricanes cause widespread damage due to their size and the heavy rainfall, storm surges, and flooding they bring¹.

- Tornadoes cause localized damage along their narrow path, but the destruction can be severe due to their high wind speeds².

Both hurricanes and tornadoes are dangerous and can cause significant damage, but understanding their differences can help in preparing for and responding to these natural disasters.

Is there anything specific you would like to know more about regarding hurricanes or tornadoes?

Q: Is there a reletionship between them

A: Yes, there is a relationship between hurricanes and tornadoes, although they are distinct phenomena. Here are some key points:

Tornadoes Within Hurricanes

- Tornadoes can form within hurricanes. When a hurricane makes landfall, the interaction with the land can create conditions favorable for tornado formation, especially in the outer rainbands of the hurricane².

Shared Atmospheric Conditions

 Both hurricanes and tornadoes are driven by **convective energy**, which involves the rising of warm, moist air². This shared mechanism means that both types of storms can occur under similar atmospheric conditions, although the specifics differ.

Differences in Formation and Behavior

- Hurricanes require warm ocean waters and form over these waters, while tornadoes typically form over land from severe thunderstorms².

- Hurricanes are large-scale systems that can last for days or weeks, whereas tornadoes are much smaller and usually last for minutes to a few hours².

Impact of Wind Shear

- Wind shear plays a crucial role in the formation of both hurricanes and tornadoes. However, hurricanes thrive in environments with low vertical wind shear, while tornadoes often form in areas with high wind shear⁴.

Understanding these relationships helps meteorologists predict and prepare for the potential impacts of these powerful storms. If you have any more questions or need further details, feel free to ask!

Q: Is there a relationship with Sea Level Rise?

A: Yes, there is a relationship between sea level rise and hurricanes, and to a lesser extent, tornadoes. Here are some key points:

Hurricanes and Sea Level Rise

- Increased Coastal Flooding: As sea levels rise, the impact of storm surges from hurricanes becomes more severe. Higher sea levels mean that storm surges can push further inland, causing more extensive flooding¹⁴.

- Intensified Storms: Warmer sea surface temperatures, which contribute to sea level rise, can also lead to more intense hurricanes. These warmer waters provide more energy for hurricanes, potentially increasing their intensity and the amount of rainfall they produce³.

Tornadoes and Sea Level Rise

- Indirect Relationship: While sea level rise does not directly cause tornadoes, the conditions that lead to more intense hurricanes (such as warmer sea surface temperatures) can also create environments conducive to tornado formation within hurricanes⁵.

Overall Impact

- Increased Risk: The combination of higher sea levels and more intense storms means that coastal areas are at greater risk of severe weather events. This can lead to more significant damage and higher costs for recovery and rebuilding¹⁴.

Understanding these relationships helps in preparing for and mitigating the impacts of these powerful storms. If you have more questions or need further details, feel free to ask!

Global sea level rise revisited

Update: so follow-on here with definions and relationsips among these topics

I posted here 3 yrs. ago among a series of DIY map notes to encourage Citizen Science, how to use NOAA global digital elevation data to model sea level rise data on straight geometry. See also here for an explanation referring to East Anglia. Here is what it looks like from the DIY document:

"Where in the world is Andrew?", updated

I posted a decade ago here re: creating dynamic maps where my travels can show on video. I have since improved on the original Mercator maps that smear out the poles and make N Hemisphere land mass look a lot bigger than it really is. 

Mercator projection (Wikipedia) started with mariners, whose maps allowed to plot sailings in straight lines. It was later kept by Colonialist Europe and Cold War North America, because it increased the size of colonizers and reduced that of the colonies, or conversely made the Soviet Union look bigger & more threatening.

Global harmonization of climate & temperature data since 1850

Update: a post in SciTech Daily shows that ocean  atmospheric science - shown in this and previous post - is alive and may help with assessing climate change: it's about the doldrums driven by downdrafts not updrafts; at a localized scale, downdrafts  were dramatically reported in passenger flight incidents here or the sinking off Sicily of a superyacht here, and updrafts in increasing mid-Atlantic hurricane generation here

CLIWOC tall ships sailings from captains logs

Update: global harmonization of climate data since 1850 follows next.

"CLImatological database of World OCeans" was my first outing using Esri tools as personal project. I found this fabulous dataset with ¼ M points! Detailed here, it came from a 5 yr. EU project to scan captains ships logs for climate data in the 17-19th c. before weather data were recorded. Tall ships were mainly British, Dutch & French, Portuguese notably absent due to Lisbon archive destruction in the 1755 "Great Earthquake" (Wikipedia).

A return to my roots

Updates: mapping climate data from historic ships & global harmonization follow respectively herehere.

 "You can get Andrew outa maps, but you can't get maps outa Andrew" quipped a GIS map friend when I left Kuwait a dozen years ago... Well after quitting socials, Esri(UK) graciously helped me recover my desktop app. While I lost my story maps and web maps content, I maintained a free dev account - story maps and maps&data - this was chiefly to preserve my Living Atlas content inspired by John Nelson

"AI for the rest of us", Part V

Update: go to the bottom for a positive aspect of what AI can automatically generate.

While I described opportunities AI gave in prompt engineering and text processing (ending at previous post here), I tried for fun to create a billboard from an advert I saw in TX or CA 20 or 30 yrs ago: it was Home Depot's "got wood?", after the wildly famous "got milk?" campaign from the Milk Board. 
Showing folks  sporting white 'mustaches' from drinking milk too eagerly, it was the dawn of the photoshop era: milk was traced into mustaches or smiles... "and no milk was spilled in the production of the advert".

Web maps for the rest of us

 The previous post on Community Engagement updated the rebranding of cambridgeshire.ai, with accompanying use of "AI for the rest of us" (work backward from here) this blogpost title came from. One of the mentioned changes were working with Wikimedia, OpenStreetMap and Climate Central - my Esri Developper or Non-Profit stacks are free and frozen, respectively - I had a whole lot of work put on ice, the same time I relinquished my original website www.zolnai.ca. This blog is OK however.

"AI for the rest of us", Part IV

Update: follow on Part V.

 The previous post (here) recapped our purpose to use current lessons-learned in new tech to help our community engagement. Here is another way to use AI, to summarise and to decant - summarise in a structured manner - information from an article my colleague asked me to try using Google Gemini (formerly known as Bard, their AI tool).

"AI for the rest of us", Part III

Update: follow on Part IV.

 Part II (here) showed a small but significant use of AI in preparing our Prospectus (link in that post). Let's look at how we're taking this further now.

The Spectator did a great state-of-the-AI here, including basically what we did above on steroids. They also highlighted Google Gemini, Bard's successor we signed up for. We also joined Wikimedia UK in open data space.
