dc.description.abstractWater sustains our cities, rural communities, businesses, industries, farms, ranches, and the natural environment. Any disruption to our water supply will significantly affect the economy and human life (Kursinski 2007). Water is an important, limited resource and any change in the hydrological cycle might result in an increase in flood or drought conditions (Kursinski 2007). Texas agricultural economies have adapted to precipitation regimes; however, they are vulnerable to precipitation anomalies, especially those that last more than one month (Lyons 1990). An analysis of 42 stations of annual and seasonal precipitation from 1932-2002 for the state of Texas is presented. Annual and seasonal total precipitation, precipitation days, and precipitation intensity are investigated using a linear regression model. Regression results reveal positive trends in annual precipitation, days with precipitation, and precipitation intensity for the southeast region. During the spring and summer months, an increase in precipitation intensity resulted for stations in the north central region, while the most notable trend during the fall months showed an increase in precipitation in the eastern half of the state, while no change resulted in the west. A decrease in precipitation days was noted for stations in south Texas, with no change in intensity or total precipitation.
