Rain and Humidity - Assignment Example process As the saturation vapor pressure varies directly with temperature, the relative humidity varies inversely with temperature. If no pee vapor were added to or removed from unsaturated air, the relative humidity increase as the temperature drops and decreases as the temperature rises. Thats why the air temperature usually rises from a minimum during sunrise to a utmost during early to mid-afternoon on a clear calm day.Question 7. Why does the amount of precipitable pissing vary with the fee-tail temperature of the troposphere? reply The average precipitable water decreases with latitude in response to the pole ward decline in the mean air temperature because evaporation and precipitable water are swallow in stale regions. Precipitable water varies from 4.0 cm in the humid tropics to less than 0.5 cm at the Polar Regions. When troposphere in middle and high latitudes is warmest during summer, the amounts of precipitable water are highe st. Question 9. Why are clouds and precipitation more likely on the windward slopes of a mountain range than the leeward slopes? effect Air that is forced to ascend the windward slopes expands and cools which increases its relative humidity. On sufficient cooling, saturation is achieved and clouds and precipitation develop.... Question 10. What is the significance of a rain shadow for agriculture? Answer A rain shadow with semi-arid to arid conditions is considered to be the boundary between dry land and rain-fed agriculture. This clime contrast affects the indigenous plant and animal communities, domestic water supply, demand for irrigation water, types of crops that can be grown, and requirements for clement shelter. Chapter 6, Critical Thinking Questions Question 2. How and why does the moisture content of the top soil affect the maximum air temperature in the lower troposphere? Answer Solar radiation genus Oestruss up the ground step to the fore that transfers heat and mois ture from top soil to the atmosphere. This heat and moisture transfer between earths surface and the atmosphere occurs by sensible heating (conduction and convection). The heated air has much more capacity to submit moisture content than cooler air. The release or absorption of latent heat affects temperature in the lower troposphere. The ascending humid air currents also expand and cool influencing the surrounding ambient air temperature. The evaporated moisture content from top soils also adds to the green house effect by trapping more infrared frequency radiation. Question 3. In late autumn or early winter, cold air flows on northwesterly winds from snow-covered ground across the glass-free waters of Lake Superior. Describe the changes in temperature, vapor pressure, and stability of the cold air as it flows over the lake. Answer In late autumn or early winter, the ice free waters of Lake Superior are warmer compared to the cold air masses flowing from the spousal relationsh ip West. When this cold air passes over the lake, the lower levels of the atmosphere take up excessive moisture and heat. The
