Geography[edit]
The Mexicali Valley is one of the largest and most fertile valleys in Mexico.[6] In the Valley, they grow over fifty different crops and it's similar in production to the Imperial Valley. National and international industries have invested in Mexicali and surrounding cities to take advantage of its tax-free status given to industry.[6] The Mexicali Valley is a primary source of water for the region, which is the largest irrigation district in Mexico.
Ecology[edit]
In spite of its arid desert location, Mexicali is watered through a system of aquifers in the valley. Under a 1944 Water Treaty, the city is "...guaranteed [an] annual quantity of 1,500,000 acre feet (1.9 km3) [of water] to be delivered..." from the Colorado River.[7] However, a proposed concrete lining in the United States on the All-American Canal would cut off billions of leaked gallons of water, which is used to irrigate onions, alfalfa, asparagus, squash and other crops in Mexicali.[8]
The nearby Cerro Prieto volcano[9] is adjacent to the Cerro Prieto Geothermal Power Station.[10] which creates high volumes of pollutants, among them, mercury. As of 2014, the government are creating a zone of exclusuion, due to the alarming amount of pollutants and contamination that has permeated throughout miles around the geothermal plant of Cerro Prieto.[11]

Because of its low annual precipitation, Mexicali has an arid climate (BWh). Under the criteria for the Köppen climate classification, Mexicali maintains desert weather temperatures every year. In December 12, 1932, the city experienced snowfall. Rainfall usually occurs in the winter months of December, January and February. Although Summer is extremely dry in Mexicali, one of every two days there is an end moisture content. In 2008, during the months of July and August there were several heavy thunderstorms that let down large amounts of rain and hail. Summer rainfall in the city is infrequent. During winter time, Mexicali is affected by the snow storms that pass by the town of La Rumorosalocated in the Sierra de Juárez, about 45 minutes west of the city, causing a decrement in temperature that lasts from two days to one week.
The summer temperatures in Mexicali are significantly higher than Tijuana, the other major city in Baja California. This is caused by the temperatures in Tijuana being moderated by the ocean, but nearby inland areas such as Mexicali being significantly hotter. However, the hot desert climate seen in Mexicali is actually not unusual for similar parallels, seen in Baghdad, Iraqfor example.
