You said the constellations were “made up” in 1922, not that their boundaries were formalized then. The earlier astronomers specified what stars were included in the new constellations. The idea that a “constellation” was not just composed of a pattern of visible stars but was defined as an area of sky that included stars not visible to the naked eye came later.
These boundaries were what were formally defined in 1922. By your definition, all constellations, even the ancient ones, were “made up” then.
For certain values of “winter.” As someone who grew up in North Dakota and still has a wardrobe of winter facemasks, I’d say that you guys have at most some fine spring weather.
I suppose this depends on the definition of European navigator.
The Periplus of the Erythraean Sea, produced by an unknown Greek author around 100 AD, describes a voyage down the coast of Africa, probably as far as the Rufiji River (7.8 degrees South). The document seems to clearly indicate that there were regular trading voyages to the areas described.
The Upper Midwest of the US experiences what’s known as a continental climate, which is known for its hot summers and cold winters. According to Wikipedia, Minneapolis has both hotter summers and colder winters than, say, Melbourne:
[ul][li]Minneapolis: Average high/low in hottest summer month (July): 29°C/18°C; Average high/low in coldest winter month (January): -5°C/-14°C[/li][li]Melbourne: Average high/low in hottest summer month (January): 26°C/14°C; Average high/low in coldest winter month (July): 14°C/6°C[/ul][/li]So I wouldn’t say that the upper midwest doesn’t get proper summer weather. It gets the extremes on both ends.
If a Sydney winter is not a “proper winter” then an average high of 29oC in the warmest month is not a “proper summer”. The average high for Darwin is is 30oC in the *coldest *winter month. Saying it is on the extreme end of *summer *weather is kind of funny. Pretty much anywhere in the tropics it’s a warm midwinter’s day.
I first read that when I was a little kid and told my dad “It’s just not fair! If Minnesota gets all that snow, they should get a cool summer. It just makes sense.”
