72,937
Explanation:
Analyzing the problem:
By 2010, population of town = 70,230
Population trend in a 5 years period:
migration
immigration: 6556
emigration: 4096
Birth 5225
Death 4978
Unknown:
The population of the town in 2015 = ?
Solution:
immigration and birth are positive factors on population
Death and emigration removes from a population
Therefore, the population in 2015 will be:
= Population 2010 + immigration + birth - death - emigration
= 70230 + 6556 + 5225 - 4096 - 4978
= 72,937

Explanation:
There are four known causes of the foehn warming and drying effect.[1] These mechanisms often act together, with their contributions varying depending on the size and shape of the mountain barrier and on the meteorological conditions, such as the upstream wind speed, temperature and humidity.
*Condensation and precipitation
، Isentropic draw-down
*Mechanical mixing
*Radiative warming
Winds of this type are also called "snow-eaters" for their ability to make snow and ice melt or sublimate rapidly. This is a result not only of the warmth of foehn air, but also its low relative humidity. Accordingly, foehn winds are known to contribute to the disintegration of ice shelves in the polar regions.[7]
Effect :
Foehn winds are notorious among mountaineers in the Alps, especially those climbing the Eiger, for whom the winds add further difficulty in ascending an already difficult peak.
They are also associated with the rapid spread of wildfires, making some regions which experience these winds particularly fire-prone.
