MOUNTAIN METEOROLOGY. Creative Writing Assignment.

Essay Instructions:

Describe and explain factors that determine air pollution potential for a city located in mountainous terrain (valley or mountains). Use Tables 12.3, and 12.4 (attached at the end) to describe how each individual factor (terrain, potential pollution sources, meteorology, climate, dispersion) influences the pollution potential (increase/decrease) at your chosen site. Explain how the concentration changes at your chosen location in the near and far field. Provide a list of source (books, articles, internet sources) that you have used and clearly state what is based on facts and what you assumed.Your work will be graded according to the following:4 points: Describing terrain (orientation, shape, height, latitude etc.) and the expected differences in solar heating between day/night and summer/winter2 points: List pollutants and sources, how are they distributed vertically and horizontally4 points: Describe flow pattern during the day and maybe differences between summer and winter. Specifically discuss up/downslope, mountain-valley, mountain-plain flow patterns at various times of the day or year.2 points: How atmospheric stability affects flow pattern and the dispersion of pollutions2 points: Describe climate relevant issues, e.g., snow cover and how it affects energy budget, typical wind patterns etc.4 Dispersion: based on the description above, summarize how pollutant will be dispersed throughout the day. Highlight possible differences in summer vs. winter2 points: Highlighting some unique feature. List of references.

* Carbon monoxide is a result of the incomplete combustion of fossil fuels and also smoke-producing cars in the cities.
* Nitrogen oxides come from combustion processes and contribute to smog formation. These can also cause adverse health issues.
* Sulfur dioxide is from burning coals and it increases acid deposition.
* Small particles such as smoke, fumes, and mists.and high rate of emission composition are air pollutants and may have adverse effects depending on the intensity of exposure.
* Man-made configuration to the environment, railroads contribute to the pollutants and their transport.
Meteorology
* The soil in San Joaquin Valley is divided into 4 groups and these are land soil, t...
