Ans:

Possible weather and associated aviation impacts for geographic / topography categories common in the western US, along the West coast of the US with steep slopes.

The west coast of the US is also called as the Pacific coast. This is a long stretch of coastal line which extends till the North Pacific. This region is identified as the coastal states of the US which include Alaska, Washington, Oregon and California.

Weather data as per the Topography / Geography

As per the data available that could affect / impact the Aviation operations is explained here. The region is expected to receive the sea breezes that originate from both sea and land temperature differences. As per theory, the landmass is expected to heat up much more quickly as compared to water body.

This difference in temperature is what creates a difference in pressure in both land and sea. The land experiences a much lower pressure built up while the sea experiences a much higher pressure built up. During the night time, the process gets reversed as air that circulates over the land cools much faster, and so the pressure that is present over the sea becomes much higher.

The increased pressure over the sea will result in the formation of the land breeze.

The next important factor that has a great impact on this region is the downslope wind factor. This is mainly caused on account of the presence of a high-pressure system, which is formed and located at the eastern side of the steep slope of the mountain range.

This results in the formation of the dry and warm winds which rushes down the high mountain slopes towards the lower sides of the plains. These blowing winds in few cases can get much stronger in speed and may also result in serious conditions.

Impacts on the Aviation

As per experts, it is important for aviation experts to be precise when calculating the wind speeds. They have to be very precise when calculating the possibilities of occurrence of strong winds that can rush down the mountain. This factor has to be considered before they make the selection of the operational runway.

The position of the runway has to be based on the factor mentioned above. It is important that they have to be very calculative in their selection.
