what are symptoms of hypothermia
sluggishness, confusion, shivering, yawning
heat emergencies
heat exhaustion and heat stroke
treatment is to cool the person down
ditty bag
a small bag that carries tools, knifes, spare parts, whistle, extra line, and other useful
parts, pieces and safety devices in a small pouch

wind velocity
speed of the wind
lull
decrease velocity of wind
puff
increase velocity of wind
wind speed knots:
light wind
medium wind
heavy wind
very heavy wind
severe heavy wind
light wind: 0-10
medium wind: 11-16
heavy wind: 17-21
very heavy wind: 22-27
severe heavy wind: 28-47
lift
winds direction shifts from the bow toward the stern
header
wind shift towards the bow
clocking wind
wind that consistently shifts in a clockwise direction
backing wind
wind that shifts in a consistently counterclockwise direction
true wind
, meteorological weather stations are always stationary, which allows them to record
accurate readings of the true wind direction and velocity
you get the true wind velocity by staying in one place
apparent wind
the altered wind direction and velocity, which is different from the true wind direction
because the motion of the weather station
boats always sail in apparent wind
what are some clues to weather change
wind direction
cloud patterns
falling temperatures
cumulus clouds
large, white, and fluffy
often an indicator of good weather
cirrus clouds
wispy, thin
usually means good weather for the day but may be a prediction that a change in
weather is on the way
cumulonimbus clouds
thunderheads, big poofy clouds
accompanied by severe weather including heavy rain and lightning
stratus clouds
low layered, stripes but thin cloud
usually brings steady rain
wind shadow
areas of less wind
thermal wind
when denser cool air is drawn towards rising warm air, wind is created
tides
the vertical movement of water caused by the gravitational pull of the earth and the
moon
most fresh water lakes dont have tides
ebbing tide
a tide that is going out or dropping
flooding tide
an incoming tide
slack tide
the period in between a ebbing and flooding tide with very little water movement
current
horizontal flow of water and is described in terms of the direction and speed the water is
moving
