How to measure rain fall when your rain gauge overflows

Most rain gauges that you will make at home will only measure up to one inch of rain fall. The problem with this is that if you live in a place where you will get more than one inch of rain your measurement if taken incorrectly will be very skewed. If your rain gauge has been constructed correctly you should have a fail safe in place.

When you construct a rain gauge you should have a measuring tube inside of an over flow tube. The meausuring tube will hold about one inch of rain fall, but when more rain falls the inside tube will overflow into the outer tube. To measure the excess rain fall you will follow a few simple steps.

Start by reading the inner tube of the rain gauge and then carefully empty the tube. Make sure that you don't pour out the water that has overflowed into the outer tube.

Once all the water for the measuring tube has been emptied carefully pour the excess rain water into the measuring tube. To get the most accurate reading try your best to not spill any water out, you can pour the water over a bucket to make sure that if you do spill any out you will catch it and be able to measure accurately.

If there is a lot of overflow you might want to measure a little bit of overflow at a time to get an accurate read. As you measure, write down the measurements and when you finish add up the values to get the reading.

The readings are done in inches so you have a reading that is 1.00 and has an overflow that measures up to .50 then the total read out will 1.50 inches.

Definition of low pressure system

Standing on the ground and looking up, you are looking through the atmosphere. It might not look like anything is there, especially if there are no clouds in the sky. But what you don't see is air - lots of it. We live at the bottom of the atmosphere and the weight of all the air above us is called air pressure. A tower of air that is 1 inch square and goes from the bottom of the atmosphere is 14.7 pounds. That means air exerts 14.7 pounds per square inch (psi) of pressure at the Earth's surface. High in the atmosphere, air pressure decreases. With less air molecules above, there is less pressure from the weight of air above.
Pressure varies from day-to-day at the Earth's surface - the bottom of the atmosphere. This is, in part, because the Earth is not equally heated by the Sun. Areas where air is warmed often have lower pressure because the warm air rises and are called low pressure systems. Places where air pressure is high are called high pressure systems.
A low pressure system has lower pressure at its center than the areas around it. Winds blow towards the low pressure, and the air rises in the atmosphere where they meet. As the air rises, the water vapor within it condenses forming clouds and often precipitation too. Because of Earth's spin and the Coriolis Effect, winds of a low pressure system swirl counterclockwise north of the equator and clockwise south of the equator. This is called cyclonic flow. On weather maps a low pressure system is labeled with red L.
A high pressure system has higher pressure at its center than the areas around it. Wind blows away from high pressure. Winds of a high pressure system swirl in the opposite direction as a low pressure system - clockwise north of the equator and counterclockwise south of the equator. This is called anticyclonic flow. Air from higher in the atmosphere sinks down to fill the space left as air blew outward. On a weather map the location of a high pressure system is labeled with a blue H.

How do we know what the pressure is? How do we know how it changes over time? Today, electronic sensors are used to measure air pressure in weather stations. The sensors are able to make continuous measurements of pressure over time. In the past, barometers were used that measured how much air pushed on a fluid such as mercury. Historically, measurements of air pressure were described as "inches of mercury." Today, meteorologists use millibars (mb) to describe air pressure.

Where is a map sensor on a 2006 chevy cobalt 2.2 4 door LS

It's on the intake manifold, black and small like a matchbox, with a three wire electrical connector. On the bottom is a rubber projection that presses into a hole in the intake manifold. To remove it, take off any retainer screws or strap, pull off the electrical connector, and pull it up out of the hole. It is on the intake because it measures the air pressure inside the manifold (manifold absolute pressure, thus the name map sensor), which is most often lower than atmospheric pressure and so therefore a vacuum.

What are the effects ol low pressure on the human body?

I assume you mean low blood pressure.
For some people, low blood pressure can signal an underlying problem, especially when it drops suddenly or is accompanied by signs and symptoms such as:
  • Dizziness or lightheadedness
  • Fainting (syncope)
  • Lack of concentration
  • Blurred vision
  • Nausea
  • Cold, clammy, pale skin
  • Rapid, shallow breathing
  • Fatigue
  • Depression
  • Thirst
  • If you mean low
    atmospheric pressure
  • When the atmospheric pressure drops, tissues expand. The expansion of tissues in and surrounding joints aggravates the nerves, causing pain. Thus, patients living in geographical locations with a higher atmospheric pressure tend to experience a greater severity of osteoarthritis (pain in the joints due to expansion of tissues). Drops in atmospheric pressure also have an impact on headaches, particularly sinus headaches. When atmospheric pressure drops (such as in an ascending airplane or before a storm), gases in the sinuses and ears are at a higher pressure than those of the surrounding air. The air pressure tries to equalize, causing pain in the face and ears. Those that suffer from chronic sinusitis or have a cold have the most issues, as the air becomes trapped in the sinuses and is unable to equalize.

The altimeter on my Timex Helix reads LO and can't be changed. I changed the battery -- anything else I can try?

Timex Helix ABT.
This watch calculates altitude by measuring air pressure and relating that value to the international standard atmosphere. 1013.25 mb = 0 metres.
The Timex ABT does not display negative altitude values. So if the measured air pressure is greater than 1013.25 mb and the altimeter is reset (select altimeter, pull out the crown 1 click and press and hold the lower left button) the watch will display LO. You can experiment with this. Wait till the barometer reads 1013 or 1012 and reset the altimeter. The watch will display zero or maybe 5 metres. Or wait till the pressure goes up to, say, 1022 and reset the altimeter. The watch will read LO again. If this happens alot, you probably live fairly close to sea level. What you can do to trick the watch is use a vacuum cleaner to raise the perceived altitude of the watch then calibrate the altimeter (pull out and rotate the crown) and change the altimeter reading to, say, 200 metres. It wont read LO then. Keep an eye on it and the atmospheric pressure. If the pressure starts to rise then adjust the altimeter accordingly. Remember this watch is designed to measure proper altitudes where the air pressure isnt likely to be as high as 1013.25. If you are mooching around near sea level the naturally changing air pressure will often make the watch read LO.
If you live up in Montana at 1500 metres (ISA standard pressure about 840 mb) all the time then the watch will always read a positive value and you can calibrate it from reference to a map or road sign etc. The atmospheric pressure will unlikely reach as high as 1013 up there and the watch wont read LO.

I have a Taylor 2750(R) Rain Guage and can not seem to get the rain amounts to inches instead of mm. Anyone have any suggestions- I have the directions, and it does not seem to address this. Thanks

I copied the following text from the users manual.

The receiver unit is factory set to diplay total rainfall in inches. To switch measurement to millimeters, press and hold the "-" butto for 3 seconds. The display will switch to mllimeters.

The trick also works to switch from mm to in.

My Weber Spirit grill produces insufficient flame after it rains.

Must be a bad regulator. Atmosphere is getting to the pressure regulator .
It is best to leave the tank attached to the grill. Even if no gas is in it to prevent atmosphere from mucking up the innards of that regulator.
