  1. The Effect of Increased Water Temperature and Air Temperature on the Increased Amount of Severe Weather The Effects of Water and Air Temperature Introduction Cove River is 15.28 acres long and belongs to the City of West Haven . Cove River is a freshwater body run-off from the salt water of Long Island Sound. Cove River is considered a watershed and consists of many deciduous trees and shrubs. The purpose of this experiment is to investigate the climate change of West Haven and the effect of increased severe weather. This experiment will be investigated by taking water and air temperature over a extended time period . This data will be analyzed to see if there is an increase which may lead to the more severe weather patterns. For example, in August 2011, Hurricane Irene moved through the city of West Haven, a rare event for this city. The chance of severe weather is related to the increase in temperatures in our city. Conclusions The purpose of this study was to gain an increased understanding of the effect of increasing temperatures and water quality on severe weather patterns. Analysis of water temperature, dissolved oxygen, pH, and phosphate data yielded the following conclusions: Temperature is negatively correlated to precipitation, so that there is less precipitation when the temperature is above average. There is a direct correlation of air temperature to the number and severity of thunderstorms, as exemplified in the early development of tornado season in the Midwest. Due to above average water and air temperatures, West Haven has seen warm seasons that last longer, enabling the early growth of much vegetation. There was no indication of increased pollutant levels in the river, meaning that there is no direct correlation between an increase in pollutant levels and more severe weather patterns. Sample site 1: Upstream Problem Statement IV: Water Temperature/Quality, Air Temperature DV: Increased Severe Weather Patterns Hypothesis: If there is an increase in water temperature and air temperature , then the warming weather patterns will develop more severe weather patterns. Sample site 3: Downstream Sample site 2: Midstream Future Directions To further investigate this experiment, water and air temperatures should be taken more frequently over a longer period of time to provide more accurate data to help prove or disprove climate change. On each occasion, water and air temperatures should be taken more than once to provide more accuracy in analyzing the results. Canopy cover should also be studied to further investigate this experiment. If the canopy cover buds earlier in the season and stays prevalent later into the season, then this shows a tendency for a warmer climate in West Haven. Soil pollution can be tested along with this experiment because the soil is capable of absorbing more pollutants than the water of the Cove River. If there is an increased amount of pollutants, it can be concluded that human activity in the West Haven area contributes to the greenhouse effect and a warmer climate. Method for Finding Water Temperature 1) Buckets, thermometers, and data equipment will be collected. 2) Water will be collected from 3 sites of the river: upstream, downstream, and in between. 3) The bucket will be thrown into the water and then pulled back up bringing water. 4) As soon as the water is collected, the temperature and amount of dissolved oxygen will be tested before its temperature can equalize with the environment. 5) Record the temperature and amount of dissolved oxygen. 6) Water samples will be brought back to the lab to be tested using Chemical Analysis Kits. 7) Record the data from the Chemical Analysis Kit. 8) Dump water that has not been chemically tested down a sink or outside and place any water that has been chemically treated in a chemical safe container to be given to a safety coordinator for disposal. Method for Finding Water Temperature 1) When at Cove River, take a thermometer and hold it outside in the air. 2) Read and record the temperature.
