Weather Generation 5: Temperature Swings

 I next generated weather matrices for four cities: Chicago, Cairo, Seattle, and Singapore. I picked these arbitrarily.

Generating their matrices taught me two things. First, it is important in some cases to account for daily shifts in temperature. For Chicago, it isn’t that relevant: here are the CDFs for temperature range, by season.

In Chicago, the 50^th percentile is about 10 degrees of difference, regardless of season. And here is the same for Cairo:

We see much more substantial temperature swings, especially in spring and summer. I found this especially important in Cairo when we are hitting mean temperatures of “Hot” (>80), because it means we can hit extreme heat during the daytime.

I don’t have a very sophisticated way to deal with this yet. I have just said: for Cairo, the GM may increase the temperature by 1 band during the day and decrease it by 1 at night if they want. I am open to suggestions about how to deal with it more effectively.
