The calls of many birds, including crows and geese, have been known to be more frequent with falling pressure. A rooster will crow as an alert message to the rest of the flock - to awaken in the morning, or to head for shelter when danger approaches. If danger approaches, then cocks apace cry."Īs the sky darkens from an approaching storm front, chickens and other birds begin to hunker down. "Take heed to the weather, the wind and the sky Here's just one of the weather tips in rhyme it offered: (You can catch Justin's weather forcasts at My great grandfather was captain of a dredge on Chesapeake Bay and, like all mariners, needed "a sharp weather eye." When he passed away, relatives going through the contents of his desk found a copy of Thomas Tusser's "Five Hundred Points of Husbandry," printed in London, England, in 1744. They graciously steered me around some potentially misleading statements and also provided some of the technical background.
#COWBOY ANALOG WEATHER INDICATOR TV#
Thanks to meteorologists Justin Liles, meteorologist at WDIO/WIRT TV in Duluth, Minnesota, and Jessie Watmore, for looking over these bits of weather folklore. South of the equator, you may have to reverse some of these sayings.) I stayed dry all day, however, while folks a few miles away from me got drenched! (Also bear in mind that these tips are for the Northern Hemisphere, where weather fronts move from west to east and storms rotate in a counter-clockwise direction. On a recent trail ride, for instance, I woke to see the classic "red sky at morning" - which generally means rain.
Remember that these indicators of weather patterns are fairly short range and may not hold for any specific location. With that in mind, here's a bunch of weather tips for you to tuck in the back of your head. It's a good idea to carry a small weather radio, but even that won't help you much if the batteries go dead or your horse accidentally steps on it. When you're out on the trail, those old weather observations can warn you about changes in the weather and possibly even save your life. Some of it wasn't reliable, but a lot was based on principles that still guide meteorologists today.Įven today, it's a good idea to have some understanding of the old-time weather lore. Over the centuries, farmers and others whose lives and livelihoods depended on the weather developed a rich treasury of weatherlore. The barometers are sorted from lowest standard deviation to highest standard deviation.Have you ever wondered what cowboys did before they had the Weather Channel? After all, a herder's life could depend on the approaching weather conditions. My results are presented in the following table. Take these results with a word of caution.
It is not my intention to pass judgement on the design of the individual aneroid barometers. In general, I don't open or lubricate my barometers unless it is obvious that they are not working properly. Most of my aneroid barometers are quite old and performance can be affected by the condition of the instrument as well as it's design. It is an indicator of how much the error changes on average with the local pressure. This is the slope of a straight line fitted to the scatter of error data points plotted against the mercury barometer local pressure, in mb per mb of barometric pressure. Finally, the average non-linearity was calculated.It is an indicator of how the error changes with time. This is simply the slope of a straight line fitted to the the scatter of error data points plotted against day of the month. The average error can be reduced by recalibration of the aneroid barometer, while the standard deviation generally cannot, it is more inherent in the performance of the barometer. 68% of the error values fall within +/- one standard deviation of the mercury barometer value. The 'standard deviation' is the standard deviation of the individual error values.The 'average error' is the average difference between the aneroid barometer pressure minus the mercury barometer pressure.For each barometer, four statistics were calcualted: The aneroid barometers were all set for local pressure to eliminate any influence of the conversion to sea level pressure on the results.
For the month of January 2017 I compared the local pressure as measured once-per-day by my mercury barometer with the local pressure as measured by 22 different aneroid barometers.
