Question 1
Patterns of Global Atmospheric Heating and Circulation
When the sun heats the earth’s surface unevenly, it results to variations in the climate of the earth. Earth’s surface heating as well as atmosphere lead the atmosphere to move while influencing the precipitation patterns. With the rising of the moist air, it later cools. Because cold has water elements unlike the case of warm air, the vapor that rising mass carries cools via the condensation process, leading to the formation of clouds. As a result, heavy rain emerges, which is connected to tropical regions, thus the mechanism that leads to the production of high precipitation within the tropics (Leinen & Sarnthein, 2012) . In the case of the mechanism that leads precipitation to soar at temperate latitudes with the rising of the air, it ends up picking moisture from desert and dry areas in low latitudes, which end up condensing to develop clouds, which later result to heavy rainfall in temperate areas. The mechanism that leads to low rainfall in tropic areas with the heating of air by the sun at the equator, it ends up expanding and rising. Also, the warm moist air cools while at the same time rising. Because cold air carries minimal water vapor unlike the case of hot air, it results to condensing of water vapor to develop clouds, which later lead to the emergence of high precipitation (Christiansen, 2014) .
Mechanisms Producing High Precipitation
When warm and humid air from south and north hemispheres, which the trade wind patterns bring as well as the resultant air convection, they meet up at the equator, which serves as the convergence zone. They result to increased precipitation amounts. This form is cycling is referred to as Hadley Cell. It results from rainy and cloudy weather based around the equator. With the condensing of vapor, gravity pulls it down to the earth’s surface. Sleet, rain, and snow serve as examples of precipitation’s mechanism. Rain emerges with the saturation of the atmosphere with vapor, which then condenses (Kusky, 2014) .

Mechanisms Producing Low Precipitation
Precipitation is mostly associated with temperature in the air. Hot air comprises of large amounts of water whereas cold air has less moisture. In the event of the tropics, temperatures are usually high while the mind carries the content of the high moisture. It does not loss the moisture unless it encounters colder air, which is mostly based in mountains leading hot air to go up. Because the tropics are normally warmer, the energy of the sun lacks sufficient energy of moving through. With the increase in the distance between the south and the north, the angle at which light energy his air increases, hence creating additional room for it to move through while the energy that comes to the ground is usually minimal. In this case, the air is normally heated slightly resulting to minimal condensation and reduced rainfall (Mason, 2015) .
Question 2
The ITCZ (Inter-Tropical Convergence Zone) refers to a segment of the surface of the earth, which attaints direct light from the sun in any instance. Because ITCZ attains light energy directly from the sun, the air ends up being unstable leading it to rise. In the event of the instability of the air, the pressure goes down. Because of heating in lie with the air’s instability, the ITCZ serves as an area characterized by low pressure. Because of reduced pressure, the molecules of the air rise up. With the ascending of the air, it cools and later condenses to establish clouds. In case it cools at a sufficient pace, it leads to the formation of rain. The ITCZ serves as the one that contributes to wet seasons in the case of the tropics. It occurs naturally in regions where the sun is directly or nearly overhead, which serves as summer in the case of the tropic areas (Leinen & Sarnthein, 2012) .
