Weather Station by Sam Epperly

The weather station I have chosen is located in Minneapolis, MN in a neighborhood called, Linden Hills. The area rests between two lakes, which define the area and social environment. The Linden Hills neighborhood is located near the 42nd parallel and falls under the classification of a humid continental climate or deciduous forest biome.

The weather station is named "KMNMINNE53" and is located at 947ft elevation. The graphs below indicate average temperature and precipitation.

Winter in this area spans almost six months and the greatest precipitation generally occurs between March and August, which coincides with the higher temperatures detected throughout the year. During the winter months (Mid October- March) much of the precipitation recieved comes in the form of snow and sticks around for a much longer period. The humidity of the region plays another important role in this consideration as the high humidity percentage allows precipitation to remain for extended periods of time regardless of the state the water falls in.

The two lakes, show above, were once swamps which contributed to the high level of primary productivity in the area as well as the dense tree clusters that dominate in the area. During the migration of more and more human populations into the region these bodies of water were cleaned and dredged of silt and seaweed, and algae. They must continue to be maintained, fighting against the constant battle brought on by artificial utrophication from surrounding affluent neighborhoods.

High concentrations and populations of trees and large volumes of water act to absorb large amounts of radiation. The typical bowen ratio for North America is about .76. Near the Linden Hills area I would expect the bowen ratio to result in a slightly smaller figure (.7-.6) because of the amount of plant life and water bodies available to absorb the insolation. While the area could be described as continental, the close proximity to the two lakes could result in more maritime like characteristics.

The area would be classified as continental, however, given the sloe proximity to the surrounding lakes, many of the characteristics might be more similar to maritime.
