Medford Oregon Average Temperatures and Precipitation



















The region I chose for my blog is Medford, Oregon. The station ID is Southwest Medford (CW2551)
. I chose this because it is my home town and sits in a valley (Rogue Valley). I thought that this may have some sort of impact on local weather. The valley aspect may affect wind patterns and precipitation in the area. Medford sits about an hour or so away from the west coast. While living there, the seasons were always apparent and not sporadic. Since I would consider Medford more Maritime than Continental, An estimated Bowen ratio I would think would be around .4 or .5, which is more than what an ocean shows, but less than the national average.

Normal Conditions (.306 Albedo, 1.0 Green House Factor)
Surface Temperature: 58.9 Degrees Fahrenheit
Energy reaching atmosphere average: 341.8 Watts/Meter squared
Energy absorbed by planet average: 390.7 Watts/Meter squared

Albedo Increased by .1 (Normal green house conditions)
Surface Temperature: 39.1 Degrees Fahrenheit
Energy reaching atmosphere average: 341.8 Watts/Meter squared
Energy Absorbed by planet average: 334.4 Watts/Meter squared

Albedo Decreased by .1 (Normal green house conditions)
Surface Temperature: 76.7 Degrees Fahrenheit
Energy reaching atmosphere average: 341.8 Watts/Meter squared
Energy absorbed by planet average: 447.0 Watts/Meter squared

Green House Factor increased by .1 (Normal albedo conditions)
Surface temperature: 63.9 Degrees Fahrenheit
Energy reaching atmosphere average: 341.8 Watts/Meter squared
Energy absorbed by planet average: 406.0 Watts/Meter squared

Green House Factor decreased by .1 (Normal albedo conditions)
Surface Temperature: 53.8 Degrees Fahrenheit
Energy reaching atmosphere average: 341.8 Watts/Meter squared
Energy absorbed by planet average: 375.3 Watts/Meter squared

These factors may cause many changes to Medford. For instance, increasing the albedo while decreasing the green house factor may result in a drastic average temperature drop since Medford is located near the ocean. Currents may become cooler due to less heat absorbed and less heat trapped within the atmosphere. These factors may also influence the amount of moisture in the air and cause a minor or major change in precipitation patterns.
