Temperature / Dew Point Relationship
The dew point, given in degrees, is the temperature at which the air can hold no more moisture. As moist, unstable air rises, clouds often form at the altitude where temperature and dew point reach the same value. At this point, the air is completely saturated, and moisture begins to condense out of the air in the form of fog, dew, frost, clouds, rain, hail, or snow.
Center of Gravity (CG).
The point at which your aircraft would perfectly balance if it were suspended at that point.
Stability of atmosphere correlates with?
its ability to resist vertical motion. A stable atmosphere makes vertical movement of air difficult. An unstable atmosphere allows an upward or downward disturbance to grow into a vertical (or convective) current.
Mean Sea Level (MSL).

Wind Shear
Wind shear is a sudden, drastic change in wind speed and/or direction over a relatively small area. Wind shear can occur at all altitudes, in all directions, and it's typically characterized by directional wind changes of 180° and speed changes of 50 knots or more.
Convective Currents
cause that bumpy, turbulent air sometimes experienced when flying at lower altitudes during warmer weather. On a low-altitude flight over different types of surfaces, updrafts are likely to occur over areas like pavement or sand, and downdrafts often occur over water or expansive areas of vegetation like a group of trees.
