A yurt in northeast Texas

[psy]

I'm very likely going to purchase a yurt to live in full time. However, I live in northeast Texas so I have a few concerns. Maybe you guys can help.

1) From browsing forums and whatnot, I understand that with

insulation

and some form of

heating

like a wood burning stove, a yurt handles the cold pretty well. But what about hot climates? I know of the many things you can do to cool a yurt:
-

Insulation

keeps cool air in
- Windows allow for airflow
- Trees block sunlight
- Foil relects sunlight
- A fan sucks hot air out
However, when imagined, it seems like the yurt would still maintain an uncomfortable heat to it. I live near the DFW area and in the summer, especially July and August, the sun beats down and it can get up to 105 degrees.

2) Yurts are round, therefore wind just flows right around them rather than hitting the resistance of a rectangular building. But this area has had a few devestating tornadoes. Is it even a good idea to invest in a yurt due to that fact?

Any information is appreciated.
