Science Exit Project: Weather
Weather itself is the state of the atmosphere at a given time. The weather seems very difficult to predict, however it is not as complicated as it seems. After looking at the variables and breaking down the pattern, a prediction can be made of the weather. The goal of this experiment is to look at the weather conditions for a given month, and then tell what shaped it, or what caused a certain variable to change.
Procedure/Materials:
First, I made a chart of the weather variables that I would be using. These were minimum and maximum temperatures, average humidity in percent, dew point temperature, and pressure. The dates I decided to use were of the entire month of October 2013. Then, using the internet, …show more content…
In the first week, the temperature slowly decreased, and the dew point increased. Then, the temperature and dew point kept decreasing, until halfway into the second week when the temperature kept decreasing but the dew point spiked up. Then, on October 17th, dew point and temperature met once again. From then, the temperature decreased a little, but the dew point dropped significantly. Suddenly, on the 30th, dew point shot up to equal the temperature. Every time that the dew point was near the temperature, there was a higher chance of precipitation. For example, on the 4th, 6th, 7th, 16th, and 30th, there was precipitation. On all of these dates, the dew point was close to the temperature. Also, the temperature trend was a decrease. This is probably because it was getting closer to winter and the angle of insolation was decreasing. The decrease probably was not very significant compared to inland cities because water retains its heat longer than land, and New York City is a coastal …show more content…
The pressure dropped on the 7th, and there was 8 mm. of rain. The pressure then increased but dropped on the 10th. This repeated on the 17th, and there was some rain as well. The pressure increased and decreased in a cyclic pattern and then dropped on the 31st again. Then, there was 1.3 mm of rain. Since air in low pressure rise, it cools adiabatically the higher up it goes. Then, it can’t hold some of its water, and the water droplets condense into clouds. When these droplets get too heavy, they fall as rain or
