Dr. Jeff Masters' WunderBlog

New product allows you to explore record-setting extreme weather
Posted by: Angela Fritz, 6:14 PM GMT en Febrero 23, 2012 +46
We've launched a new extreme weather product this week: Record Extremes. Recent, globally record-setting years have demanded a product that combines U.S. and international record extremes into one, easy to use interface. The Record Extremes page will give you the option to see U.S. and international records on a map and table. You can select any combination of record types at once, which, combined with the map, provides a interesting visual way to investigate record-setting events. The product uses data from three sources: (1) NOAA's National Climate Data Center, (2) Wunderground's U.S. records, and (3) Wunderground's International records.

The NCDC records begin in 1850 and include official NOAA record extreme events for ASOS and COOP weather stations in all 50 U.S. states as well as Puerto Rico, the Virgin Islands, and the Pacific Islands. In this database you can find records for maximum high temps, minimum high temps, maximum low temps, minimum high temps, snow, and precipitation on daily, monthly, and all-time scales.

The Wunderground extremes were compiled by our weather historian Christopher C. Burt. Chris monitors 300 stations across the U.S. for Record Extremes in maximum and minimum temperature, precipitation, and snow events. Most of these U.S. records go back to the end of the 19th century, though the oldest site in this database is Charleston, SC, where precipitation records started in 1737! Internationally, Chris monitors 150 countries worldwide for all-time record high temperatures and all-time record low temperatures. If you're interested in diving deeper into extreme weather in the U.S. and abroad, Chris's book Extreme Weather is an excellent resource.



Figure 1. All-time snow records broken during the Groundhog Day Blizzard of 2011. These records were found by selecting NCDC as the source, a start date of 2011-01-31, an end date of 2011-02-02, "maximum snowfall," and "all-time."


We built the Record Extremes product to make it easy to find specific records you're looking for, or just browse the records in general.

Check records that were set on a specific date
You can check on records that were set yesterday, for example, by setting the calendar to yesterday's date, and selecting all the record variables and types that you're interested in.

Explore all records set in a certain time range
2011 was a record-setting year for the U.S., and most of the records were high maximum temp and high minimum temps. To see all of these warm records that were set last year, select "NCDC" as the source, 2011-01-01 as the start date and 2011-12-31 as the end date. Select Maximum High Temp and Maximum Low Temp in weather variables, and select all-time in the record type.

View current standing international records in the Wunderground database
Select either the Wunderground International records, and instead of choosing a date range, select "Show current standing records." This will bring up all standing records in the database for whatever record variable and type you select. Whereas we've collected every record ever set or broken from NCDC, the Wunderground records are always the current, standing record, whenever it was set. As you move your map around the globe, you'll see each country's all-time maximum high temp and all-time maximum low temp.

Filter your table results
Looking for a specific location or record within your search results? Use the "Filter Results" option in the table to narrow down your search.

Let us know what you think!

Quoting Jax82:
Looks like they better install some wind shield wipers and put on some slicks on those stock cars, thats the only way they'll race today.

It's pretty wet throughout the region now and still dripping. For the sake of the working people who are race fans, I hope they have an early evening start.

Quoting ScottLincoln:


Contrails are not being "used" for anything. They are a bi-product of air travel and any affect on weather/climate is a consequence of demand for that service. Effect of contrails on climate has substantial error bars - some papers have suggested a net warming effect, while others have suggested a cooling effect. A commonly-held understanding of high clouds is that they tend to produce a net cooling effect, while low clouds tend to produce a net warming effect. See "global dimming."


I misspoke, meant to type chemtrails there- the intentional spraying not related to air travel.

airplanes do not create water vapor... another preposterous citing from the weather mod non-sense...
the condensing of water vapor in a parcel of atmosphere is not an addition of more water molecules. no additional greenhouse impact occurs when this happens; in fact, the cloud most likely contributes to cooling (as mentioned per global dimming).
i'm just spouting this off the cuff, no scientific citing needed, because this seems to me to be weather 101... and if the conspiracy theorists can get the most basic stuff right... well then

Define "conspiracy theorist", you believe anything that's not spoon-fed to you can't be happening? The Manhattan project had tens of thousands of people working on it without the general public knowing about it, I understand that now we're living in an era where people have been conditioned to have an immediate Pavlovian response to picture tinfoil hats at even the mention of the word "conspiracy", like Pavlov's dog salivating when hearing his bell being rung. I'd at least read the scholarly research that has been done on it in the links provided before spouting off the cuff. The father of the modern environmental movement "We are as Gods" Stewart Brand says spraying sulfur dioxide will cool the planet and proclaims any criticism of geo-engineering a "heresy"

it's pretty simple... if it's about a conspiracy, and using facts that neither corroborate nor fall within the scope of reasonableness, than it is a conspiracy theory.

conspiracies exist, they are exposed all the time. but then, scientific facts exists, which are also exposed all the time. it's up to you, whomever you are, to not lose sight of where information comes from, what it leads to, and the way it fits into that which is the observable reality where we actually reside as physical beings.

i don't feed from the spoon, fellow blogger. i reach in for myself, and choose the items that are edible, having had the experience of tasting the inedible... to extend your metaphor.

Heartland.. now there's an exposed conspiracy, which was clearly evident as such due to the countless release of information deemed false, contradictory, and laden with fallacy.. and the argument that weather modification is under way by governments has, for me, exhibited an equal amount of mis-characterized and misinformed dissemination.
wxmod has shown us many pics of China smog... now There is weather modification indeed.. but there is nothing in the sense of logic and reason that informs us the smog is a result of China's desire to modify weather. no -it is a result of productivity desires, such as are ALL of the motivations behind activity whereby humans are actually modifying weather.

aside from cloud seeding, no successful attempts at government-based weather modification seem to be present; at least by my personal standards of evidential support.
but, we all get a voice ;)

Aircraft engines like all internal combustion engines do create water... it is a byproduct of combustion.

Slow Soaking Rain!!! YEA! Our Crops IS SAVVEDD!
or at least the drought is lessened in the region of NE FL.

The long black shadows from Contrails above winter stratus layers seems much more prevalent this year.
Some days the sky looks like a loose weave fabric from all the trails.
The "dove in a hole" ice precipitate, definitely does handle light differently than surrounding cloud layers. See my sundog images.

After one of the largest snowstorms in this decade, I got a snow day today! :D First one since 2009.

Snow totals for the storm aren't out yet though.

One thing for sure, there seems to be more and more contrails, the airline business seems to be doing better these days.

The airline industry is growing yes, but not doing better. A few airlines here and there are doing good (JetBlue), but the rest are about as profitable as AA, which just filed for chapter 11. This decade, I wouldn't be surprised if many airlines simply disappear, especially the larger ones.

i will admit, i was incorrect on this. thinking it a recycled emission, and correlating the contrail with particulate soot condensing the already present vapor, i had not been aware of a 30% water vapor output by jet fuel. i feel like a heel calling the notion preposterous.

however, nothing has changed in my thoughts on motivated weather modification efforts. i just don't see a concerted conspiracy with air travel.. i see the unfortunate outcomes of an over eager global society.

I think the number of airline flights have stayed about constant for the last few years. Contrails are dependent on the density altitude and that varies day to day.

Big rains coming to most of Australia.
Flood warning have been issued, Flash flood warning have been issued. This could be a very big event.
