Problem
Pick your location and briefly explain why it is your favorite place. What is the climate there (using the Köppen system) and what are the contributing factors for having that climate? So for Orange County don't just say we are Csb and winter wet and summer dry. Say WHY we are winter wet and summer dry. Say WHY we are Csb and not Csa. Refer to your lecture notes and textbook. Do not just search "Irvine Climate" as you may get the wrong answer.
1) No Highland climates (so no Big Bear, Mammoth, Machu Picchu, etc.)
2) Pick a specific place/location you can determine the Climate for. So you can't just say "Costa Rica", because it has 4 different types.
Include name of place, briefly why it is your favorite, the climate info indicated above and if the climate is a factor in favoring the place.
