Artificial ways to alter rainfall patterns! According to a new study, Phoenix and other arid region cities create some artificial conditions to change the pattern of rainfall as desired or wanted.
With a 12 to 14 percent increase in rainfall in the northeast suburbs of Phoenix — from the pre-urban period (1895-1949) to post-urban (1950-2003) — an entirely new ecosystem has developed around Phoenix. This change did not occur in a day, or just by a natural process. This water-cycle is human induced – by introducing urban irrigation. Thus, this method can prove effective even under arid or drought conditions.
Water resource management, agricultural efficiency and urban planning have turned Phoenix into a paradise. The Journal of Arid Environments published this study online. This study relied on rainfall data and records from NASA’s Tropical Rainfall Measuring Mission (TRMM) satellite.
