Yay condescension. Heat waves are caused by heat domes, and they don't have clouds https://www.washingtonpost.com/weather/2021/07/10/heat-dome-heat-wave-faq/ h

  Heat waves != Heat domes Yes the 49C event in Vancouver and surrounding areas was a heat dome and didn't have clouds. Where I live, just a bit earlier we had complete cloud cover for an entire day w/ "feels like 40C" hot and humid weather. It didn't rain that day, except once a little sprinkle. It made it muggier outside than it was before.

    That's not a heatwave that's just heat.

      Agreed. It's a heatwave when this kind of weather (hot/dry, hot/normal, hot/humid) persists. Sometimes in combinations of these conditions. Something that is a heat wave in one place might just be called 'weather' in another place. If New Delhi got our "regular winter weather", it would be called way more than a "cold spell", while 2 weeks of New Delhi weather here is called a heat wave.

      Well, so what do you call a whole week of constant 34℃ during the day, but with clouds in the sky and even a brief (but intense) rain once? That's what we had last week in Poland.
