Natural Disasters of 2020

In addition to all the other problems of 2020, it was also a record setting year for natural disasters in the United States and worldwide. In the U.S. there were 22 weather and climate disasters with losses exceeding $1 billion. The previous record for this scale of loss was 16 in 2011 and 2017. These disasters also caused 262 deaths. Here's a map from NOAA.

Climate Central has maps showing number of disasters by state (this is all billion dollar events since 1980),

and more interestingly by type, though they should have picked a more clearly distinct color for TROPICS.

Finally, here's a map from Reddit showing disaster type by county. 


Like most things on Reddit there are many caveats. Unlike most things on Reddit the author was good enough to include them here.

The Remarkable Maps of Mr. Tornado

Last night I watched "The Remarkable Mind of Mr. Tornado" on PBS. Tetsuya "Ted" Fujita was a pioneer in meteorology, known for developing the F-scale to measure tornadoes. His studies led him to draw many maps of this nature.
What I enjoyed the most was his personal maps. When he was invited to the University of Chicago to work with professor Horace Byers, he experienced his first airplane flight. During the flight he drew this charming map showing the clouds he passed through on a multi-day flight with two stopovers on Wake Island and in Hawaii.

Via PBS, "American Experience"
This map is a bit hard to read at this size so here is some detail. Click the picture above to see the entire map at higher resolution.
In his own words "Without wasting the expensive flight time, I began sketching the vertical time cross section of clouds along the flight path. Shortly before 1600 JST, the aircraft flew into towering cumuli, encountering severe turbulence. I heard crashing sounds of dishes and utensils in the flight kitchen. A moment after, the flight became smooth and I saw a beautiful arc of low clouds.”

After settling in Chicago he began to document his travel throughout the United States and Canada, first by railroad, then by car.
https://www-tc.pbs.org/wgbh/americanexperience/media/filer_public_thumbnails/filer_public/59/52/5952720f-777a-446f-af6e-ecffc9789e28/tornado-memoir_us-canada-mt0735m_ttu.jpg__1000x709_q85_crop_subsampling-2.jpg
He traveled through every state except Rhode Island. According to the map he only missed it by a few miles. I have chronicled my own travels in this manner but not with nearly as much charm or detail.

Highlights of this map include the tornado-chasing squiggles through Oklahoma and the green elevation contours.

Earth Animations

Earth is a project from Cameron Beccario showing a wide range of climatic conditions that can be animated. Here are the winds animated from Hurricane Florence as it made landfall on September 14th.
At the same time an even more intense Typhoon Mangkhut battering the Philippines.
You can choose to look at air or ocean currents, waves, water and air temperatures (at different heights)  and various other factors. You can even switch map projections. Here are ocean waves using the Waterman Butterfly projection,
and ocean currents in the North Atlantic, looking very Van Gogh-like.
Data are from various global sensors, the geographic data comes from Natural Earth. The visualizations are created in the browser using javascript programming. The color schemes are intuitive enough that no legend is required. Here is the three hour precipitation accumulation over North Carolina from the hurricane.
Another option is the probability of seeing an aurora.

Aerosol Earth

NASA's Earth Observatory created this stunning image of aerosols - airborne particles and liquid droplets.
https://eoimages.gsfc.nasa.gov/images/imagerecords/92000/92654/atmosphere_geo5_2018235.png
These aerosols "range in size from a few nanometers—less than the width of the smallest viruses—to several several tens of micrometers—about the diameter of human hair. Despite their small size, they have major impacts on our climate and our health." - via NASA aerosol page

In the image above blue represents sea salt. The concentrated areas show major storms, particularly two cyclones off the coasts of Japan and Korea and a hurricane approaching Hawaii. Red indicates black carbon, mostly from agricultural burning in Africa and Wildfires. Purple is dust, mostly from deserts. Also included is a layer of white night light data to indicate urban areas. Here is the legend enlarged for emphasis.
The NASA page includes a zoomed in detail from southern Asia, emphasizing the deserts, cyclones and population centers of the area.

Awful Hurricane Inspires Cartographic Greatness

At the risk of minimizing an awful tragedy, Hurricane Harvey has inspired some wonderful maps, particularly from the New York Times and Washington Post. This animation from the Times is spectacular. Click the play button and watch it unfold.
The subtle dark circles indicating areas of peak rainfall create a remarkable sense of the storm's movement.

The Washington Post's cube showing the total rainfall is also pretty remarkable.
https://www.washingtonpost.com/news/capital-weather-gang/wp/2017/08/27/texas-flood-disaster-harvey-has-unloaded-9-trillion-tons-of-water/?tid=graphics-story&utm_term=.c92fead7bb78
This only shows what rain had fallen as of August 27th so the situation has gotten much worse. In fact, here is an animation they just put on Twitter.
They did a nice job highlighting buildings and areas on the background map.

The total rainfall map is also quite striking. I lost the text on the image below but you almost don't need it. You can see the entire map with city labels, precipitation totals, legends and all by clicking on the picture.
https://www.washingtonpost.com/graphics/2017/national/harvey-impact/?utm_term=.59c3b4a0ab9d
Their map of rain gauges is also excellent.The arrows almost give it a three dimensional effect.
https://www.washingtonpost.com/graphics/2017/national/harvey-houston-flooding/?utm_term=.1266d16af560
I tried to break out of the New York/Washington media to see what other maps are out there but these really are much better than anything else I've seen. The Houston Chronicle has little to offer for maps though they do have an impressive collection of photos of the devastation and rescue efforts. What is encouraging is to see many articles about cooking, sports and politics showing that life is getting back to normal for at least some people in the area.

Misleading Buffalo Snow Maps

As we prepare to spend Thanksgiving with my wife's family in western New York, here are some maps of what we could be in for. This one, posted on Flowing Data a few years ago does a nice job of showing the lake effect snowbelt south of Buffalo. But there are problems...
http://flowingdata.com/2007/09/27/misleading-map-of-buffalo-snow/
Green implies that the rest of the area including Buffalo (inside the dashed box) is not so bad. However, a look at the legend shows that green is up to 80 inches a year and the yellow that appears in many of the suburbs is 90-100 inches. Chautauqua County people may consider 80 inches to be minor but for the rest of us this color choice is terribly misleading.

The map also may need an update as parts of the region are getting half their average this week.
http://lintvwwlp.files.wordpress.com/2014/11/wivb-snowfall-map.jpg
 Be "4 Warned" - this is another misleading map. How much snow will we see in Rochester? Apparently nothing even though family members tell us otherwise. The dropoff from 18-24" to nothing at the Livingston-Wyoming county line is remarkable as is the sudden lack of snow in Erie County, Pennsylvania. No data and no snow are not the same thing so don't treat them the same.

The Great Lakes Storm of 1913

100 years ago today was the beginning of the Great Lakes Storm, the most deadly and destructive storm to ever hit the region. Also known as the "White Hurricane" because of the blinding snow that fell, the storm killed over 250 people, destroyed 19 ships and stranded 19 ships and some additional cargo barges. The storm raged for several days with a few lulls that only served to give false hope to stranded mariners. Most of the destruction occurred in Lake Huron. Wikipedia has this excellent map, originally from the USGS showing sunken ships in black and stranded ones in gray. Click for the original, more readable image.
The storm intensified and built up to hurricane force on November 9th. The US Weather Bureau only issued reports twice a day so most of this build up was not noted until too late. Cleveland saw 22 inches of snow and lost power for days as did much of the region. Breakwaters were destroyed in Chicago and Milwaukee.
   
There is a story on NPR's Morning Edition on the search for two ships in Lake Huron that have never been found. Another interesting account of the attempts by some crews to survive can be found in The Paragraph.

Oklahoma Destruction

The New York Times put together an excellent map showing the extent of destruction from Monday's tornado in Moore, Oklahoma. The map is based on a visual survey of the aerial photography. It shows that at least 1,500 buildings were destroyed or severely damaged, including entire neighborhoods.


It's truly amazing what nature can do in a few minutes and there's lots of voyeuristic photos on the web page - just be thankful if you're not one of the thousands of people affected.

Watch the Snow Fall

The National Weather Service has a Snow Analyses page where you can see current regional and national conditions. You can also see animations of the yearly snowfall as well as snowpack depth, temperature and sublimation. Here is a still photo from today showing the storm that just came through the Midwest.

Once again, purple is the scary color. This one, from February 9th shows the storm that hit the Northeast.

Today's snowpack temperature:

If you're stuck indoors today from the snow,  choose a region, date range and topic and watch the snow fly (or melt.)

Purple is the New Scary

With winter storm Nemo* bearing down on us the weather cartographers have decided that purple is now the scary color. Kind of like the recent Australia maps except this time indicating snow instead of heat.

Maps are from The Weather Channel. Apparently oblique is now the scary map angle. Working in the "Action" zone, I just set up our town's emergency mapping function - sounds more exciting than it really is.
So hunker down and buy all the bread and milk you can find, it's going to be a purple day for many of us. 

* Since when do they name snow storms? It used to always be the Blizzard of (Insert Year Here.)

The Wind

Someone sent me a link to the Wind Map a while ago and I forgot about it until yesterday when a friend reminded me of it. Meant to help us see the potential of wind power, it's also pretty cool during a hurricane. Had I not been so busy yesterday trying to put together maps of power outages and downed trees, I could have posted a map that looked like this:

Here is a detailed view of Hurricane Sandy and its huge area of influence. I love the way it highlights our most important cities like Columbus.







 Today, conditions are a little more scattered but still pretty intense over the Midwest:

 
Here is what it looked like in southern Louisiana during Hurricane Isaac this past summer- this picture came from the Washington Post but the original link is broken:

Speaking of which the Post has an excellent graphic of the storm's impact:

Thanks to Molly for the Wind Map link.

Storm of the Week

Here in the Northeast we are still dealing with the tail end of the Groundhog Day Storm-another week, another storm. This map posted yesterday on AccuWeather nicely shows how big this storm was (or still is up here) with advisories in 43 states.

 

Each color represents a different type of advisory and they range from severe thunderstorms to blizzards, gales, floods, wind, wind chill, marine warnings, high surf, dense fog, air stagnation and my personal favorite, heavy freezing spray.  I think that last one is along the lakes of northern Michigan but with so many colors it's tough to distinguish. The most common colors are the dark purply blue (winter storm), purply pink (blizzard), orange (wind chill) and the brown stuff in the south that I think is a wind advisory.

Despite the ugly projection, strange inclusion and exclusion of certain cities (especially in eastern Canada), and gratuitous topography that is easily mistaken for other weather patterns, the map still tells a pretty impressive story.  Punxsutawney Phil says early spring-yeah, right. Have fun digging!

Another Good BBC Map

In addition to the nice Sudan maps (previous post), BBC also has an excellent map of Brisbane, Australia showing the extent of the floods and major points of interest. Note that the yellow area is flooded area at the predicted water height and the flood appears to have peaked at slightly below that level.

Map of the Week-Hurricane Season Again

Hurricane season is upon us again. According to a Penn State study (reported by the BBC), Atlantic hurricanes are more frequent than at any point in the last 1000 years. At the moment the Atlantic is fairly quiet. There is a tropical depression named "Two" that is losing strength - details from the National Hurricane Center.


Maps from the National Climatic Data Center show where hurricanes have struck land in the Eastern United States since 1950. Unfortunately the resolution on this image is fairly low and the higher resolution version is 40 MB and will likely take your computer an hour or more to download - perhaps they want you to buy the poster?

Today's Weather Forecast-Sunny in the Deserts, Rainy in the Rainforests

I was looking something up on CNN when I came across these weather maps. What's remarkable (or not) is how well they seem to conform to the climate zone patterns of the world. I poorly stitched together the southern hemisphere continents minus Australia (too hard to deal with the scale difference there). I had to rotate Asia for projection issues. Anyway here's a comparison.

Map of the Week - Under a Cover of Snow

Here in the Northeastern USA we got hit with a pretty big storm March 1st and 2nd. I've had worse but my back is pretty sore from shoveling. NASA's Earth Observatory put this picture up as their Image of the Day for today (March 4th). The image was taken from NASA's Terra satellite.

Seems like some of the traditionally snowy areas were mostly missed such as the Rochester-Buffalo-Toronto area, parts of the Adirondacks and the Alleghenies while Delaware looks like it got it bad. The "cloud streets" over the ocean are pretty cool.

Map of the Week - Stay Indoors!

I'm not a regular at NOAA's weather pages so I don't know how typical this is but today's weather map sure looks scary-and colorful too! The legend was hard to copy and paste and is hard to read anyway. You can click the image to get to their interactive map and see what you should be scared of in your back yard. We've got advisories on boats, wind, avalanches, floods, fire, gales, snow storms (I'm watching one as I type), cold and fog. Even Hawaii's in on the action with surf advisories. The ten plagues! One of the safest places to be today is Alaska.
Have a great New Year, stay warm and dry!
