What does the drought monitor measure?
Unlike most of the weather maps people see in the news, the U.S. Drought Monitor is not a forecast. In fact, it looks backward. It’s a weekly assessment of drought conditions, based on how much precipitation did or didn’t fall, up to the Tuesday morning before the map comes out.
What caused the drought in Texas 2011?
What Is Causing the Drought? The main culprit of the intense 2011 dryness was La Niña, a weather pattern where the surface temperatures are cooler in the Pacific. This in turn creates drier, warmer weather in the southern U.S. (You may also know her counterpart, El Niño, which generally has the opposite effect.)
