Historical Weather Patterns of Michigan Essay Example for Free

Historical Weather Patterns of international mile EssayEvaluating changes in synoptic patterns is tantamount to understanding regional mode change. To date, the synoptic evaluations that have been through with(p) regarding climate change output from General Circulation Models have been restricted mainly to examining changes in storm tracks across large areas.The north generally experiences colder weather compared to the south, but air mile weather is unpredictable and switches rapidly, especially during the winter (Hodak, 21-28).Seasons and types of weatherfall, cool nights and warm days wintersnowy and constantly cold, getting dark early in the evening springwarmer days, much rainy with thunderstorms summerhot days and warm nights, daylight lasting until late in the evening (Bohnak, 87-95). People hunch over to talk or so the weather. From Maine to the Midwest, locals are convinced that their weather conditions are the weirdest. Theyll tell you about the big blizzard, t he spacious flood, or the hideous humidity, convinced that decades of harsh weather have shaped the characters of the local people (Keen, 19-27).Relationships surrounded by springtime heat accumulation and low temperature events in the western Lower Peninsula were investigated. Sixty years (1931-1990) of routine maximum and borderline temperature data from six seats were used to calculate seasonal growing percentage point day (GDD) accumulation normal and uttermost(prenominal)sand their relationship to the date of last block up at each station throughout the period. Results indicate that in spite of a wide range of individual station and year-to-year variability, both(prenominal) regional springtime GDD accumulation thresholds and last freeze dates are occurring earlier but the timing of GDD thresholds is ever-changing more rapidly, resulting in a net trend toward more freezes after certain GDD thresholds are get over and a flat or increasing amount of GDDs accumulated on the date of last freeze (Keith, 35-41).Extreme low temperature events are a normal range of springtime climatology in Michigan and goat cause severe damage to many of the states diverse agricultural crops. In particular, late spring freezes are a major concern in the western counties of the Lower Peninsula where commercial fruit production is laborious and their occurrence may be a significant factor in explaining inter-annual variations of yield (Hodak, 21-28). For example, a serial publication of freezing nights in late May 1992, damaged several types of fruit (grapes, strawberries, plums, and sweet cherries), reducing the overall potential size of the crop. Although United States mean temperatures have been rising during the last decade, perhaps as part of a wider global trend, some recent springs have been particularly warm in Michigan (e.g. 1991), extreme low temperature events continue to occur (Keen, 19-27).The possible association between regional temperature trends and the risk of exposure of extreme minimum daily temperature events has not been widely examined. Some efforts have focused on documenting recent changes in the duration of the growing season or on the relationship between mean temperature trends, but little is gettable concerning Michigan (Keith, 35-41).Furthermore, recent literature is largely silent on the question of how springtime low temperature risk is conditioned by antecedent weather patterns, that is, for example, whether a warm April is normally followed by a lower-than-average hoarfrost risk in May. Regardless, to the extent to which climatological findings of this type could be generalized from one climatic region to other is uncertain, so such relationships established elsewhere might carry very little information about the risk in Michigan (Bohnak,87-95).One important relationship between human activities and the atmosphere is contamination. The wellness effects of polluted air and the ways in which humans and soci ety can reduce pollution are ideas that are considered in the middle and high school benchmarks. At the high school level, in particular, this includes a discussion of global warming and acid rain. Interestingly, one issue for the teaching of these topics is the exclusive tie-in between air pollution and human activities with lack of regard for other natural sources of air pollution, such as burning leaves, fireplaces, volcanoes and methane gas from cows (Keen, 19-27).All of the changes are consistent with changes in the general large-scale flow patterns. An understanding of all these synoptic changes provides richness and a more conceptual understanding of how climate change may affect the Great Lakes region.ReferencesBohnak, Karl, So Cold a Sky Upper Michigan Weather Stories, Cold Sky Publishing, Negaunee, MI, pp. 87-95Hodak, J.
