What I mean by climate/temperature is a mix of precipitations and temperature across the year and not just the annual mean because I suspect that using the average does not give a good idea for crop yield. Some place have harsh temperatures in winter but also a hot summer. While some other places have a short winter but the temperatures rarely go over 15 degrees in the summer. My guess is that the first place will be able to grow more food thus might have a higher population density.

Does anyone have a guide or an article about this ?
