425 CONCLUSIONS: The use of wind-tunnel for sea breeze study can produced a steady flow pattern, so there is plenty of time for taking quantitative measurements. But the cost is great. Using water tank experiments, the flow pattern established is of a short time span. tank experiment is the ease in flow visualization. taken, they can be studied in good time. operation is ridiculously low. The advantage in water After photographs are The cost of equipment and For air pollution meteorologist, the height of the sea breeze is the most important parameter for stack height determination. The water tank experiment can provide a quick and inexpensive method of obtaining this information for rough terrain.
