Persian Gulf Experiences Record (and Life-Threatening) Heat Index (msn.com) 105

Parts of the Persian Gulf "have seen the heat index, or how it feels when factoring in the humidity, reach 140 to 150 degrees Fahrenheit (60 to 65 Celsius)," reports the Washington Post, "fueled by an intense heat dome, the warmest water temperatures in the world and the influence of human-caused climate change." Temperatures at the Persian Gulf International Airport in Asaluyeh, Iran, climbed to 108 (42 C) on Wednesday and 106 (41 C) on Thursday, with both days recording a peak heat index of 149 (65 C). In Dubai, the temperature topped out at 113 (45 C) on Tuesday and the heat index soared to 144 (62 C). Other extreme heat indexes in recent days include 141 (61 C) in Abu Dhabi and 136 (58 C) at Khasab Air Base in Oman.

Last August, this same region experienced even more extreme heat indexes, climbing as high as 158 degrees (70 C).

The maximum air temperatures this week — generally between 105 and 115 (41 and 46 C) — have only been somewhat above normal. But the dew points — which are a measure of humidity — have been excessive, climbing well into the 80s (27 to 32 C). In the United States, any dew point over 70 degrees (21 C) is considered uncomfortably humid. It's the very high dew points that have propelled heat indexes up to 30 degrees (16 C) above actual air temperatures. The extreme humidity levels are tied to bathtub-like water temperatures in the Persian Gulf, the warmest in the world. According to National Oceanic and Atmospheric Administration data, sea surface temperatures are as warm as 95 degrees (35 C).

Largely because of the high humidity, nighttime minimum temperatures have also remained exceptionally warm, in many cases staying above 85 (29 C). Temperatures in Iranshar, Iran, only dropped to 97 (36 C) on Wednesday night, its hottest July night on record.

"Researchers have identified the Persian Gulf among the regions most likely to regularly exceed life-threatening heat thresholds during the next 30 to 50 years," the article adds. And it also cites new heat records reported for the region by weather historian Maximiliano Herrera. "The United Arab Emirates saw a scorching high temperature of 123 while Adrar, Algeria, tied its record of 122 (50 C). Cities in both Kuwait and Iraq reached 126 (52 C), and Al Ahsa, Saudi Arabia, notched a record of 124 (51 C)...

"The same heat dome that's in the Persian Gulf region has spread record heat northward into Eastern Europe, westward into northern Africa, and eastward into India, Pakistan and Indonesia. In Eastern Europe, high temperatures surpassed 104 (40 C), with some locations staying above 85 degrees (29 C) at night."

    I learned this little trick when I was a kid by watching rabbits do this.

    I used to do this under a big tree in the back yard near the rabbit burrow during the summer when it was well over 100F in SoCal.

    It works very well, in fact it worked so well that if I fell asleep for an hour or two I'd wake up cold kind of like falling asleep in the tub.

    The best part was that the rabbits would come over and lick the sweat off of me... if you've never had a rabbit lick you you're missing out.

      Your houses must have been poorly designed. Airconditioning is a comfort not a necessity in virtually every climate. But we've lost the lessons of the past. Even 500 years ago arabs knew how to build houses to funnel cold air in and hot air out. For much of the 19th and 20th century we in the west even knew how to face windows and position houses in the prevailing wind direction.

      These days, we care about style over function, and just throw an airconditioning unit in. It's amazing how poorly we build houses these days.

            Yep, if the average temperature of the air and ground is too high, a passively-cooled house is never going to get cool enough without assistance (i.e, proper phase-change air conditioning). Sure, good design can make it "less awful" but it's still not a nice place to be, and it's worse if the inhabitants need to get meaningful work done, as opposed to just sipping cool drinks and watching other people toil in the plantation.

        It's partly down to towns and cities, i.e. the density of the housing making freely aligning a house and ensuring good airflow is difficult. It gets even worse with blocks of apartments where most of them don't have two opposing exterior walls.

        Thing is even the Arabs would have had a hard time with the humidity and heat. When it's not too humid your body can shed heat into the cooler air much more easily.

        • No it doesn't. That's simply the result of shithouse town planning. There's nothing about density that prevents a town planner from adopting the architectural lessons of how to manage heat.

          Again it's a pointless stylistic choice. The "I want to be fancy and don't want this neighbourhood to look like every house faces the same direction" style of design.

    I was stationed in southern Bahrain during Desert Shield/Storm back in '90-'91 during my time in the Corps. During the day the temps would regularly get above 110F with uncomfortable but manageable humidity levels and at night no lower than 85F with damn near 95% humidity. It's was brutal and miserable to say the least while living in a tent the entire time. I actually went water skiing in the Persian Gulf a few months after I got there and the water was very warm, much warmer than Lake Erie where I grew up, and Erie can reach as high as 82 during warm summers. Sounds to me like conditions have not changed all that much. Fun fact, the aircraft I worked on would get so hot during the day that we couldn't work on them for fear of blistering our hands. We did most of our maintenance at night.

      • I'm not sure if this was planned or not, but right around the time Desert Storm officially kicked in (Jan 17th) it happened to be the "rainy" season for the area. It rained for a few days (no more than five if I remember correctly) and the extremely hot daytime weather subsided a bit for the remainder of Desert Storm. This allowed us the opportunity to service the planes during the day since they were involved with performing flight operations all night long.

    During and after the COVID shutdown it was noticed in the global temperature tracking-and-modeling community that some industrial and transportation "air pollution" had a COOLING effect. Further (like volcanic pollution) it clears out (like volcanic pollution) or builds up in a time scale of a couple years, rather than the decades-to-centuries time scale of greenhouse gasses. Some significant components of this effect are fine dusts from industrial activity, high-altitude exhaust from commercial aviation (dust and contrails), and, massively, sulfur emissions from shipping (increasing and brightening over-ocean clouds).

    In particular, as of a few months ago it was estimated that the reduction of shipping sulfur emission, due to the recently rolling-out global limits on sulfur in ship fuel (previously cheap but high sulfur), plus the reduction in shipping due to the COVID supply-chain disruptions, MORE that accounted for ALL the sea-level water temperature increase since the limits started going into effect. (That may not be current now, as shipping picks up post-COVID lockdown but using still lower sulfur fuel as the limits become more effective).

    Deliberately adding sulfur to ship fuel to increase the global cooling part of the balance (as had been proposed even before this) has it's own problems. But perhaps modifying ships' cooling water and exhaust systems to introduce sea-water spray (which dries to cloud-seeding particles) into the hot exhaust and vent it to the air could produce the same effect without adding any more or different "pollution" than increased wave-action (as from storms) would.

    Meanwhile, regardless of how much the added CO2 from previous industrial fossil fuel consumption may have contributed to heating the planet, it looks like slamming on the brakes may end up with a century or two of GREATER heating, and that a cut-CO2 solution would have involve tapering off the emissions without depressing manufacturing and transportation, over a period of decades.

    Which, just incidentally, is exactly what the rollout of renewable energy, now driven more by economics and recent technology improvements than government promotion, has been doing (or had been before the draconian interference with the US fossil fuel industry.)

    I am annoyed with misleading headlines and articles. Heat index is not ambient air temperature, but it makes it feel hotter than it is due to evaporation not happening due to already saturated air. Starting out by saying outrageous temperatures imply not a heat index. I want to slap the editor that let this misleading article get published. The world record for straight temperature which is 134.1F on July 10, 1913 at Furnace Creek, Death Valley, California. Maybe if someone paves a big parking lot there that record will eventually be broken.

    The record heat index temperature is 178F in Dhahran, Saudi Arabia on July 8, 2003. So a sensational article saying 140 or 150F is really declaring that it's a slow news day.
