H
hail:
precipitation in the form of ice pellets that are a result of upward moving air currents that pull the liquid rain upward, then freeze the rain due to the decreasing temperature with higher altitude.  
H
halo:
a ring that appears around a source of light such as the sun, moon or even a street light.   Image of halo
H
heat:

H
high pressure area:
a particular region in which the atmospheric pressure is elevated above standard conditions. In this area the wind moves in an outward direction and clockwise around a center in the northern hemisphere, and counter-clockwise in the southern hemisphere.
