What hard chart or information would you take with you?

[Wise Old Owl]

I happen to have a pack of Nat Geo Adventure Paper and I got to thinking it would be really cool to take a few charts with me for next years hikes that would be advantageous to have to get a clear picture of the enviornment.... So I will post a few I thought would be nice to have, such a hard copy of important phone numbers. A list of observations of weather. A solstice list. etc. You as the reader might have other ideas as to what you might bring like a naked eye star chart or wind chill chart. I have a few you might not recognise..... There are some reasons for this that I will post later. The first is below and barometric pressure is read off of the Garmin Vista

Here are some general statements of wind-barometer indications that are generally applicable to all parts of the country:

"When the wind sets in form points between south and southeast and the barometer falls steadily, a storm is approaching from the west or northwest, and its center will pass near or north of the observer within 12 to 24 hours, with wind shifting to the northwest by way of south and southwest.
"When the wind sets in from points between east and northeast and the barometer falls steadily, a storm is approaching from the south or southwest, and its center will pass near or to the south of the observer within 12 to 24 hours, with winds shifting to northwest by way of north. The rapidity of the storm's approach and its intensity will be indicated by the rate and amount of the fall in the barometer.
"As a rule, winds from the east quadrants and falling barometric pressure indicate foul weather, and winds shifting to the west quadrants indicate clearing and fair weather, but again there are exceptions and in some parts of the country these rules do not apply."
The following table generally summarizes wind and barometer indications in the United States. The amateur forecaster should modify the table in accordance with his or her own observations. The following show the wind direction, the barometer reduced to sea level and the character of the weather indicated:

SW to NW, 30.10 to 30.20 and steady - Fair with slight temperature change for 1 to 2 days.
SW to NW, 30.10 to 30.20 and rising rapidly - Fair, followed within 2 days by rain.
SW to NW, 30.20 and above and stationary - Continued fair, with no decided temperature change.
SW to NW, 30.20 and above and falling slowly - Slowly rising temperature and fair for 2 days.
S to SE, 30.10 to 30.20 and falling slowly - Rain within 24 hours.
S to SE, 30.10 to 30.20 and falling rapidly - Wind increasing in force, with rain within 12 to 24 hours.
SE to NE, 30.10 to 30.20 and falling slowly - Rain in 12 to 18 hours.
SE to NE, 30.10 to 30.20 and falling rapidly - Increasing wind, and rain within 12 hours.
E to NE, 30.10 and above and falling slowly - In summer, with light winds, rain may not fall for several days. In winter, rain within 24 hours.
E to NE, 30.10 and above and falling rapidly - In summer, rain probably within 12 to 24 hours. In winter, rain or snow, with increasing winds, will often set in when the barometer begins to fall and the wind sets in from the NE.
SE to NE, 30.00 or below and falling slowly - Rain will continue 1 to 2 days. SE to NE, 30.00 or below and falling rapidly - Rain, with high wind, followed, within 36 hours by clearing, and in winter by colder.
S to SW, 30.00 or below and rising slowly - Clearing within a few hours, and fair for several days.
S to E, 29.80 or below and falling rapidly - Severe storm imminent, followed within 24 hours, by clearing, and in winter by colder.
E to N, 29.80 or below and falling rapidly - Severe northeast gale and heavy precipitation; in winter, heavy snow, followed by a cold wave.


Going to W, 29.80 or below and rising rapidly - Clearing and colder.

I had a boat that would do forty knots. ;)

Is this for 2009? Very cool.

i would definitely take the knots, i always end up screwing up whatever type of knot i started out to tie. It ends in a giant junk knot that gets rained on and tighter overnight. Leaving me scratching my head in the morning...."how the heck do I untie that"

What is this? Can u explain please?

[sheepdog]

moon chart???

[mrhughes1982]

Yeah I couldn't figure out how to read it.

Month >
Day V

I would suggest that wind direction and, to a lesser degree barometric pressure at altitude, are modified by ridge lines and that the windward slopes are ALWAYS at higher pressure than leeward. An east-west wind WILL shift northward along a mountain ridge.

Its the moon chart for 2010 the days of the month run top to bottom and the months are left to right. Hense the second column is February!

I think we did something simmilar a little over a month ago it was -3 degrees for 1000 feet of elevation, that's my guess as I tried searching for the thread and cannot find it. I was unaware the barometric pressure would be dramatically different on a ridge line.

HHmmmm let me see...I hate knots especially when they get tied up in all the tree roots that cross the trail...Trip over them every time..hehehehe...The moon chart I guess would be nice, IF you could see the bloody moon on the trail...
The wind chart.. I have never been able to gauge the wind. I mean how do you know what speed the wind is blowing with out a gauge and I suspect that would be added weight.. If I am being blown to the next pass, yep, I say it is too windy....

As for a rain chart... I tend to look at the leaves on the trees, (when there is leaves).. If the velvet side of the leif is turned up the tree will have a silvertint to the cover... It will rain in the next couple of days...and if the trail amazingly looks like a river, yep, its raining,, an dif that river all of a sudden turns to mud, yep, its been raining.... and more rain is coming...

so much for charts.... But hey they could make for good reading in the privies...:D:D

Might be a bit old - Pa I think is now 13 degrees...

[Nicksaari]

i like to carry a nice fold up hard chart of the native flora. hell, throw a knot chart and maybe an edible species chart as well. learn and teach, spread the knowledge, bc knowledge is power
