"H"
H Designated letter for "HAZE"
Hail: Jagged or round ice chunks that fall from thunderstorms.
Above pictures are of 2 onions I cut to simulate hail. When hail is cut in half
1...If you cut a hailstone in half you will be able to count the rings. Each ring represents
Hail Size: Pea/Dime/Nickle/Quarter/Marble/Egg/Baseball/Softball/Grapefruit. 1/4", 1/2", 3/4" and larger size hail has occurred.
"HALOS"
Haze: Extremely small dry particles invisible to the eye suspended in the atmosphere.
"Example" Max 70
Min 50
---------
Mean 60
Surtract the mean temerature of 60 Degs. from 65 Degs. We now have 5 Heating Degree Days for that day.
Heat Index: The heat index is the combination of the temperature and the relative humidity. When combing these two the result is how hot the air feels.
"H E A T W A VE"
Heat Wave: An extended period of hot temperatures and high humidity.
"Heat Island"
Hook Echo: A pattern on a radar scope which resembles a hook often associated with a tornado.
"The Horse Latitudes"
1. The "Horse Latitudes" located at: 30-35 Dgs. N. & S. Latitudes. Are areas of
little or no wind.
2. With the wind calm ships could not move fast enough to their destinations
and ran out of food and water for the horses.
3. The horses were then thrown overboard. Thus lightening the load of the ships.
4. Thus the name "The Horse Latitudes"
Horse Latitudes: An area of calm winds at about 30 degs. North and South Latitudes.

11. Hurricane: Eye: 10 mi. diameter. Can be 100 mi. dia.
12. Hurricane: Forward speed up to 50 mph.
13. Hurricane: High & Low tides. Full Moon or New Moon produce higher
storm surge.

23. Hurricane: Pacific Centers. San Francisco, Honolulu
24. Hurricane: Pacific Season: May 15 to Nov. 30.
25. Hurricane: Prepartion for hurrricane vary expensive.
26. Hurricane: Safety: Civil Defense Evacuation. FEMA.
27. Hurricane: Saffir-Simpson Scale. 1-5
28. Hurricane: Spanish For Evil Spirt.
29. Hurricane: Storm surge maybe up to 50 miles wide.
30. Hurricane: Storm Surge moves inland 300 to 700 feet.
31. Hurricane: Storm Surge strongest part of storms.
32. Hurricane: Storm surge with high & low tides.
33. Hurricane: Typhoon. Chiness for Hurricane.
34. Hurricane: Warm Core Storm.
35. Hurricane: Watches/Warnings/Advisories/Bullitens issued by the National
Weather Service.
36. Hurricane: Water must be 80 degs. F.
37. Hurricane: When crosses Atlantic to Pacific given new name.
38. Hurricane: Winds strongest on front side of storm.
Hydrologic Cycle: The continuous transfer of water through "Sensible Heat", "Latent Heat". (Conduction-Convection-Condensation)
from oceans, lakes, etc back to the atmosphere and Vis-Vis.

Haboob: A desert dust storm.
..........When the hail is cut is half, it contains rings for each time it rose and fell in the storm and resembles and onion.
- 
- 
it has rings which resemble and onion. If you count the rings, that would be how
many times the hail was sent up and down in the thunderstorm.
.....how many times the hailstone rose and fell in the thunderstorm.
2...If the hailstone has 5 rings that means it went up and down 5 times in the storm.
3...Inside a thunderstorm are strong updrafts and downdrafts. When water droplets are
.....caught by an updraft , the updraft takes it above the freezing level (32 Degs. F.),
.....It then freezes and becomes ice (Hail).
4...If the (Hail) is caught in a downdraft it will be brought back down below the freezing level.
5...As it falls down below the freezing level it picks up moisture. The hail will then get caught
....in an updraft bringing it back above the freezing level once again.
6...The new moisture on the hail will then freeze and another layer of ice will form in the hailstone.

1...Hail occurs in thunderstorms.
2...Hail is classified by size such as:
3...Pea Size...Nickle Size...Quarter Size...Half Dollar Size...Pingball Size
.....Baseball Size...Softball Size...Golf Ball Size...Tennis Ball Sise...Grapefruit Size.
4...Hail is usually round but can be flatten and also occur in jagged lumps.
5...One of the largest hailstones which fell was in Nebraska in 2003. Had a diameter of
.....of 7 inches. It was almost 19 inchs around and weighed about 1 pound.
6...Sometimes there are 25 layers of ice in a large hailstone.
7...Hail causes billions of dollars of damage a year to crops and property.
8...Hail is usually associated with severe thunderstorms and sometimes indicates tornado
.....activity, however, there can be hail without any tornado acticity.
9...In observing hail, it is classified as "SNOW." It is not uncommon to have 4 to 6 inches of Hail.
10..When large hail is falling one should seek shelter indoors.
Hail Size: One of the largest hailstones fell in Nebraska in 1928. It was 17 inches around and weighed 1.5 lbs.
Hail Size: Sometimes there are 25 layers of a large hailstone.
Hail Shaft: An area in the upper level of a thunderstorm where hail is thrown out of a thunderstorm.
Hail Streak: A long path of hail which has fallen on the ground.
Halo: A ring around the sun or moon produced by refraction of light through ice crystals.
Head Wind: When facing into the wind the wind is coming toward you.
Heat: Anything that does work produces heat.
Hear Equator: An area at about 10 degs. N. Latitude with high yearly average temperatures.
Heating Degree Days: Heating Degree days are based on a mean temperature of 65 Degrees.
To arrive at the mean temperature add the max and min temperature for the day, divide by 2 to get the mean or average for that day.
If the mean temperature is below 65 degrees than we have "Heating Degree Days" for that day.
Heat Lightning: Heat Lightning is a term used when lightning is seen from a thunderstorm that
is to far away for the observer to hear thunder. The term probably came about due to the fact that
thunderstorms usually occure when the air temperature is warm.
1. Slow down in hot weather:
2. Dress for summer wear white loose fitting clothing.
3. Stay out of direct sunlight.
4. Don't get too much sun.
5. Do not eat heavy foods.
6. Drink plenty of fresh water or other non-alcoholic drinks.
7. Stay in an air conditioned area.
8. Restrict your activity.
9. When at home in the house, keep curtians and blinds closed during the daylight hours.
Heavy Snow Warning: A snowfall of at least 4 inches in 12 hours or 6 inches in 24 hours.
High: An area of high pressure: Anticyclonic.
High Pressure:Moves towards low pressure.
High Pressure: The winds are "Clockwise" (CW) in Northern Hemisphere. Move outward away from the center. Centrifugal force.
Hight Wind Warning: Sustained winds of at 40 mph or gusts of 50 mph or greater are expected to last at 1 hour.
Hoar Frost: Crystalline ice which forms on surfaces that are below freezing. Appear like feathers, needles, leaves, ferns.
Horizon: A distant point from the observer where the sky and the ground meet.
Human Body Temperature: 98.6 Degs. F., 37.0 Degs. C.
Hurricane:A tropical cyclone, low pressure system. A weather system which has no fronts and is generated by the warm waters of about 80 degs. F.
which it receives its enery from. Having wind speeds of 74 mph or greater up to over 200 mph.
Hurricane Warning: Issued when a hurricane is expected in a specific area within 24 hours or less.
The Atlantic Hurricane Season June 1 to November 30.
The Pacific Hurricane Season: May 15 to November 30.
Hydrostatic Equilibrium: The balance between gravity force and vertical force air movement.
