Why are there heatwaves for years beyond 2006? Begreen 19:42, 25 March 2006 (UTC)

Some believe Global warming is the reason for the current heat wave, future heat waves. Martial Law 19:02, 21 July 2006 (UTC)

A reference to the IPCC summary should be included, esp. the section which highlights the increased risk of extreme weather events such as heat waves with rises in average global temperatures. Having one newspaper reference at [9] is poor form. 90.213.18.30 (talk) 19:27, 5 February 2011 (UTC)

Current Heat Wave

Can someone state that the 2006 Heat Wave is going on right NOW

in the United States ? Sources are the two weather sites, FOX News, CNN, other news sources. I heard that fatalities have happened already. Martial Law 04:25, 17 July 2006 (UTC)

I cannot confirm the fatality reports. Martial Law 04:27, 17 July 2006 (UTC)

I haven't heard of a great deal of fatalities yet. It isn't exactly article-worthy at this point anyway - they need to often last weeks, not days, to raise the fatality rates and smash the records. Though a new wave could be building in this weekend... CrazyC83 19:45, 17 July 2006 (UTC)

The FOX News, other news agencies, the two weather websites have actually declared that there are heat warnings and heat advisories being issued, now for nearly all of the U.S. Martial Law 21:12, 17 July 2006 (UTC)

Heat wave Europe

This morning it has been confirmed that 2006 has its second heat wave in The Netherlands. This one is forecast to last at least another week, maybe even 10 days more. It also confirms that there are heat waves in France, Spain and Portugal. The last two countries are warning of extreme temperatures. http://www.knmi.nl/VinkCMS/news_detail.jsp?id=33185 (In Dutch)

The BBC and the British meterological office also speak of a heat wave in the UK. The met office has issued heat warnings to the National Health Service. http://news.bbc.co.uk/1/hi/uk/5193486.stm Bikerams 08:56, 19 July 2006 (UTC)

- Heat wave in parts of USA, most parts of Europe (UK, Benelex, Spain, Germany) and for what i've read also in Australia. Suggestion: create an article '2006 World Heat Wave?' Marminnetje 14:44, 19 July 2006 (UTC)

Physical damage

Several areas are reporting that the current heat wave has caused all manner of damage. In Shreveport, LA, it has caused water mains and lines to burst, and in other areas, it has caused roads to serverely buckle and crack. A Satellite link error is fouling my sig and causing me to log out automatically, so, please excuse the sig. If you live in a area affected by this heat wave, your news source will have more info.

United States definition

I have found three sources (all .pdf city emergency/hazard plans) which refer to the "3 or more consecutive days above 90°F" stipulation as an official National Weather Service definition, or imply it due to other sections which refer to it[1](page 33),[2](down right now),[3](page 40); however, I can't find that specific definition anywhere on the NWS website, so either they're hiding it, or, more likely, the definition was discontinued recently (recently enough that countless media outlets referred to it this summer). Can anyone add? i have a heat wave in my ass

FWIW, whenever I do various Google searches, I find the statement in one-time NWS statements...example, as of the current time Mapsax 21:47, 8 August 2006 (UTC)ther is a big heat wave in the desert

Cause?

I looked and didn't find that the article gave a cause for heat waves. Does anyone know what is the cause? I know that global warming is said to be part of the cause, but what is the full cause? --Meraculas 20:54, 14 January 2007 (UTC)

I have now inserted what I know and what I have found about heat waves and the reasons that they happen. It is suprisingly difficult to find the information. I had to put a collection of different reasons to which they occur together from all the different causes I know of. This is because there is not one single cause. Heat waves are caused by many factors. --84.65.94.156 12:15, 3 September 2007 (UTC)

Definition

A peer-reviewed definition from the Glossary of Meteorology:

heat wave—(Also called hot wave, warm wave.) A period of abnormally and uncomfortably hot and usually humid weather.

To be a heat wave such a period should last at least one day, but conventionally it lasts from several days to several weeks. In 1900, A. T. Burrows more rigidly defined a “hot wave” as a spell of three or more days on each of which the maximum shade temperature reaches or exceeds 90°F. More realistically, the comfort criteria for any one region are dependent upon the normal conditions of that region. In the eastern United States, heat waves generally build up with southerly winds on the western flank of an anticyclone centered over the southeastern states, the air being warmed by passage over a land surface heated by the sun. See also hot wind.

Fatalities

I have read that cold temperature extremes cause more deaths on average in the United States than heat waves. This article says the opposite. So I guess someone needs to find the source for that.

Risk of death

A meta-analysis has looked at the risk of death and factors that may improve or worsen the risk: doi:10.1001/archinte.167.20.ira70009 JFW | T@lk 21:30, 13 August 2007 (UTC)

Limited Scope and Biased

I think the incidents etc are very biased in the sense that they present primarily a European/American/Australian definition of a heat wave. The temperatures mentioned are very much common in countries like India and major parts of Africa. A four day stretch of 40 C+ temperatures is normal. In fact places like Ahmedabad in western India are known to have the high temperature for the whole month of April and May above 40 C. The page on Geography of Ahmedabad can be used of reference which shows that temperatures remains in the 40's throughout the months of March to June.

A more thorough research of the weather records is required for this article to be complete and exhaustive.

Possible Heatwave

There may be a possible Hemispheric Heatwave soon. A good example is what happened in 2006 in BOTH Europe, North America, Asia when heat waves struck at the same time thus qualifying that one to be a "Hemispheric Heat wave" since the Northern Hemisphere was affected. 205.240.146.121 (talk) 16:57, 8 May 2008 (UTC)

2008 Heat Wave/ 2008 Heat Storm

This just started in the Southern US. Temps are in the high 90s, humidity is in the 40-50+% range, heat index is in the 100s. Affected areas are Texas, Louisiana, Oklahoma to the Atlantic Ocean and to the Gulf of Mexico. 65.163.115.204 (talk) 20:53, 6 June 2008 (UTC)

Got another (possible) one that may be starting up, as of the sig time here. Temps are already in the HIGH 90s.65.173.105.27 (talk) 20:24, 8 July 2008 (UTC)

This is now definate. Dallas and points East, south and north as well as the West will have 100 degree temps AS highs for several days. See NOAA and the Weather Channel for more. This is a confirmed heat wave folks.65.173.105.27 (talk) 06:47, 10 July 2008 (UTC)

This is a confirmed event that is going on.65.163.117.135 (talk) 04:19, 3 August 2008 (UTC)

Pic

In general, I am not against pictures to illustrate a point. However, the current picture next to Mortality to, I suppose, illustrate perspriation is completly out of place. Hot chicks are great and all, but it is not representative of the kind of danger a heat wave causes. This chick is not dying of heat stock, she is glistening from a work out. 07:55, 1 February 2009 (UTC)75.177.47.137 (talk) 23:48, 19 January 2010 (UTC)

Spelling

I think that the usual spelling is heatwave as used by the SES and government etc. Cgoodwin (talk) 01:48, 17 February 2009 (UTC)

Thats true but the problem is this article is a World wide article and different countries have there own way of spelling "heatwave"[4]. I think you will also find that US spelling has been used for the article[5]. Bidgee (talk) 01:57, 17 February 2009 (UTC)

Prediction

Although it will be too late when this is added, perhaps a section on PREDICTING them? All forms of weather can (or should be able to) be predicted, so....

Perhaps the techniques used to predict them? That would be helpful to people wanting to learn about that. —Preceding unsigned comment added by 64.233.227.21 (talk) 21:28, 9 February 2010 (UTC)

Copy Edit donation from Severe weather

Heat waves are generally capable of occurring at any geographic location. These weather phenomenon usually occur when large quantities of cool, dry air masses become stationary over an area for long periods of time. Warm, moist air from the Gulf of Mexico, the Mediterranean sea or any other large bodies of water then become presented underneath the stationary cool air mass. The cool air masses causes process of inversion to occur, which is unsuitable for clouds to develop. Without the presence of clouds, more severe radiation can be exposed upon an area, causing temperatures to increase at rapid rates.

This information is from the Severe weather article and my fit better here. Respectfully Bullock ✉ 03:36, 29 May 2010 (UTC)

How they occur

Cnrwil004 (talk) 22:28, 3 March 2012 (UTC)This section contains no references and some of the ideas seem contradictory or suspicious. For example, the lack of high level clouds and low humidity in deserts can hardly constitute a cause of heat waves in such regions. Also, in the South-western Cape of South Africa, where I stay, heat waves are usually associated with low (not high) pressure systems, responsible for off-shore flow, a mechanism I suspect may also at work during heat wave episodes along the eastern and southern coasts of Australia.

Also, the section is copied from [[6]], and is almost certainly copyrighted.

I did find a good source on the formation of heat waves from the US National Weather Service, and used it to replace the copyrighted material. This and several other sources confirm the role of high pressure. Perhaps there is a different mechanism in the parts of the world you mention. Sagredo^{⊙☿♀♁♂♃♄} 05:22, 25 March 2012 (UTC)

Merge Heat Storm

The article Heat storm is a defintion WP:Dictionary for the same event. It's contents should be moved here and the article turned into a redirect.Sagredo^{⊙☿♀♁♂♃♄} 18:56, 23 March 2012 (UTC)

Support. There shouldn't have ever been an article called a heat storm. Famartin (talk) 22:12, 23 March 2012 (UTC)
