Chicago Jan. High: 31

Atlanta Jan. High: 52

DC Jan. High : 44

You tell me which one DC is closer to temp wise.
DC has an average January low of -2c in the middle of the UHI. That is not subtropical. Atlanta would be about the coldest a subtropical climate should be.

?
Depends how growing season is defined. In the UK it's starts when there are 5 consecutive days with a mean of 5c or higher, and ends when there are 5 days with a mean below 5c. By that definition, London's growing season is about 340 days.

Using the first and last frost dates would give around 250-260 days at Heathrow and about 320-360 days in the centre.

So you exclude place like Wuhan to be subtropical ???

In the north of Washington D.C. winter tend to be too cold and summer less hotter, therefore, it's difficult to considered continental subtropical the places above D.C., these cities are more humid continental.

I don't know why you are obsessed with rainfall defining a climate & call places with average lows of below freezing subtropical, yet somewhere where there has never been a temperature recorded below freezing isn't, just because it doesn't have "handsome" summer rain

So please stop stating your own personal opinions as fact
Temperature are not the decisive factor, all factors are important.

Yes, the winters in Wuhan are too cold, they're similar to here.

Wuhan winter to cold, ok it's a joke...
And do you take account of the incredibly tropical summer with some of the highest dew point on Earth ? Do you take account of the length of the growing seasons ? Do you take account that this city has 9 month with a mean of more than 10°C ? Do you take account of the length of the summer (5 month over 22°C mean) ?

That counts for nothing if the winter is too cold. Winters are more important than summers for subtropical climates. Brisbane and Hong Kong are subtropical, Las Palmas, Malta and Rome are subtropical. Wuhan, NYC, DC are not.

No, sorry but in a climatic point of view, all factors are important, if the warm seasons is long and hot enough, the "cold" winter (if the mean of the coldest month aren’t too cold, in other words, a mean over 2°C) are compensate (and the winter in Wuhan are not cold, the coldest month, January, has a mean of 4.6°C and both other winter months have a mean of respectively 6.9°C for December and 7.1°C for February, it's not cold).

Dec: 6.6c
Jan: 4.2c
Feb: 6.3c
Winter: 5.7c

That is not a subtropical winter.

well I've seen people use the claim of subtropical/tropical plants being able to grow in a particular place makes it also subtropical, but plants are pretty adaptable and can grow in a wide variety of climates, and are very good at coming back from the brink of death. However you can still use a similar concept, but with animals, which are not so good at adapting, especially if you exclude mammals. So I nominate a very typical subtropical animal that has a hard time surviving outside of its climatic zone, the American Alligator, here is it's range.


https://upload.wikimedia.org/wikiped.../Rangemapx.gif

I think that is a fairly good representation of the humid subtropical climate range in the US, it might continue a little bit more outside of the highlighted area, but not by much in my opinion. Also the southern tip of Florida is tropical and can be represented by the range of the American Crocodile.

Now these only represent the more wetter climates, so inland texas might be a more arid subtropical climate, but it's just too dry for the alligator to thrive in. Also I wonder if there is map depicting the historical range of the Chinese Alligator since it's current range is very limited.
