For example, when a colder air mass … Examples of intensive properties include temperature, refractive index, density, and hardness of an object. Railway tracks are bent or broken. IDK. Latent heat of vaporization acquired at low latitudes is thereby delivered to, Because they entrain much more water vapor and latent heat, tropical, storms and hurricanes are greater contributors to poleward heat transport than. An ideal source region should be extensive, broadly uniform with gentle, divergent air circulation. An air mass acquires its temperature and humidity through exchange with the surface. Just as an air mass took on the properties of its source region, it tends to take on properties of the underlying surface when it moves away from its source region, thus becoming modified. geology C. weatherology ® meteorology D. none of these. The degree of modification depends on the speed with which the air mass moves, the nature of the region over which it moves, and the temperature difference between the new surface and the air mass.

A given volume of air at 20°C (68°F) can hold twice the amount of water vapor than at 10°C (50°F). They transport latent heat, thus removing the latitudinal heat balance. Concrete dikes and foundation of bridges are destroyed by ground settling or toppling. The physical properties of an air mass are determined on the basis of the characteristic features of the surface through which it travels. Estimate the amount of power needed to operate the air-conditioner. a) maritime polar. The air masses carry atmospheric moisture from oceans to continents and cause precipitation over landmasses.

Bridges and elevated concrete structures are toppled or destroyed C. People find it difficult to stand even outdoors. The Properties Of An Air Mass Depend On A. Drag depends on the properties of the fluid and on the size, shape, and speed of the object. So the temperature and humidity of a particular location depends partly on the characteristics of the air mass that sits over it. d) continental polar. The related intensive quantity is the density which is independent of the amount. Dry air is a mixture of gases where the average molecular weight (or molar mass) can be calculated by adding the weight of each component. What would happen to the speed of a wave if a P wave were to go through a liquid medium and then through a solid medium? At high latitudes, the surface waters cool.
