Wabash Watershed - Essay Example There is also a relevant trend for the cycle of increase of temperature if we based it on the average annual maximum temperature in the Wabash valley watershed based on the 5-year and 10-year data from 1961 to 1990. It started higher somewhere in 1961 then went to a downward spiral somewhere in 1981 and 1982, but again it surged higher back to the temperature equivalent to almost one unit experienced in 1961 based on a 10-year covered data. The above trends are consistent with the overall trend of the average annual temperature in the Wabash valley watershed. There is a remarkable cycle of temperature increase, starting with the lower one in 1961, then a relative increase along the way, and decrease in 1981 and again a remarkable increase of the graph slope until 1990. This trend significantly shows a cycle of temperature increase, but reveals us the point that in totality there is an observed temperature increase within the range of time between the years 1961 to 1990. To look at it a specific level, we can also observe the average daily temperature range in the Wabash valley watershed. The graphical representation shows a downward trend from 1961 to 1990 based on the average 5 and 10-year data. This is in fulfilment to the envisioned scenario of some theorists that there is a more pronounced warming of minimum temperatures than maximum temperatures, which we can relatively observe as realistic if we based in on the graphical trend representations. Furthermore, this could be observed from a reduced range of temperatures, which we significantly see from the decreasing trend of the average daily temperature from 1961 to 1990, as the 5-year and 10-year average data show. The evidence of drought and water surplus To investigate the evidence of drought and water surplus conditions for inland or continental locations, we can look at the trends in precipitation amounts and the frequency of certain amounts of precipitation taking place at Wabash valley watershed. Glob al warming theorists believe that global warming phenomenon foresees drought and less surplus water conditions for inland or continental locations. The average annual precipitation in the Wabash valley watershed generally has an increasing trend starting from 1961 to 1990 and if we also based it on the 5-year and 10-year data. On the average annual days of light precipitation in the Wabash valley watershed, the trend remarkably goes high and even higher starting from 1982 to 1990, 5-year and 10-year data. This trend is also remarkably observed if we based it on the average annual days of precipitation in the Wabash valley watershed, as there is a depiction of increasing trend from 1961 to 1990. On the other hand, the average annual surplus in the Wabash valley watershed relatively increases to fewer inches, higher in fewer inches from 1961 compared to the level in 1990. Between these corresponding years, there is also evidence to suggest that the surplus level tends to maintain a hi gher trend compared from 1961. Expectation from a warming climate As there is evidence to support the overall warming of the environment based on the data generated from Wabash valley watershed, the average annual actual evapotranspiration has an increasing trend starting from 1961 to 1990.
