Drier air means more variation. Both are right. The nature and number of the factors that affect weather keep meteorologists guessing. Elevation, latitude, distance from the ocean, ocean temperature, moisture and air mass movement determine weather in a specific area, said Taylor, Oregon's climatologist. And with such mutable ingredients, it's no wonder that weather remains understandably unpredictable.
Some factors have a greater effect on climate, while others affect weather more.
And if you're not sure about the difference in the two, Taylor makes it plain. Weather is what you get. Or, climate tells you what to buy, and weather tells you what to wear. Moisture, ocean temperature and movement of air masses have more of an effect on daily conditions. The further you move from the Earth's surface, air pressure is lower and temperatures are cooler.
