🌡️ The current heatwave in Asia is really troubling. It is one of the worst in recorded history.
From South East Asia to the Indian Subcontinent to West Asia, no country is being is being spared.
The record maximums are in high 40s in many regions and the most terrifying is the record minimums, with many regions have over 30 C night temps.
☀️ Day: 47.5 in Nawabshah, Pakistan
🌑 Night: 34.3C in Khassab, Oman
India and Pakistan suffer a too-early heatwave again.
Kachelmann has station measurements for cloudiness (Bedeckungsgrad des Himmels",
relative humidity ("Relative Luftfeuchtigkeit")
and temperature

During the midday 3-hour period today, quite a few weather stations in the Northern parts reported the lethal outdoor-combination in %rel.humidity with °C for old people age 65+.
But I think, the also reported cloudiness was a life-saver for those who couldn't stay indoors. Clouds lessen the heat stress.
A table in Vanos et al 2023 shows the unsurvivable combination of temperature and % relative humidity for young and old people, indoors/shaded and outdoors/sun-exposed.

(only look at the lines starting with
Corresponding Tair (°C). The other lines are sciency and a bit confusing.
)
Figure 4 in the paper shows the livability-thresholds, meaning, how hot+humid can it get for which activity, from merely sitting to heavy lifting. Very useful.

Heat & survival: African Wild Asses vs Wet-Bulb Temps.
Hunting was the old threat. Now, they fight livestock for shrinking waterholes. We can hide indoors, but they just wait in the shade. Suffocating heat is choking them.
When does this heat break us? Working outside in summer might soon be impossible.

今回は、アフリカノロバ（学名：Equus africanus）と「家畜と湿球温度」といった、ちょっと怖い話です。この種は、2014年の図鑑では、民間療法の薬の材料として狩猟されていたことが主な理由で、「CR：深刻な危機」とされていました。そして最新のレッドリストでも、気候変動による干ばつなどの影響が重なって「CR：深刻な危機」のままなんです。だからアフリカノロバは今も、「湿った熱が、命を塞ぐ」そんな状態なのだと思います。この記事は短く、5分で読めます。よかったら最後まで読んでください。
THE HEAT IS ON!
The #Heat #Advisory today could be expanded to an #Extreme Heat #Warning for the southern half of the #Northland Friday afternoon and evening. The feel like #temperature could be around 100°, with #wetbulb globe temperatures in the upper half of the 80s.
Overall, the next few days will be handled best with plenty of #water, shade, and rest in cool places.
@ai6yr How hot is too hot? A good explainer about #wetbulb temperature.
