Weather and Instruments:

Weather is constantly changing and is the state of the atmosphere.

It can also be referred to as meterorology. Which is the study of
the earth's atmosphere. Scientists use all different kinds of instruments
to measure different types of weather. Each and every instrument has
there own way of functioning and the units measured. Below will be some
examples of different instruments that are used.

A common instrument that is used to measure weather is the thermometer. The thermometer is used to measure the temperature or temperature gradient. The thermometer has two important elements. There are two kinds of thermometers, primary and secondary. Thermometers measure in farenheit and degrees celcius. More information can be found here. Image found.












Another instrument is a Barometer. A Barometer measures air pressure. It can measure the pressure excerted by the atmosphere by using water or air. It is measured in MBARS (millibars). It works by balancing a weight of mercury against the atmospheric pressure just like two weights. If the atmopheric pressure weighs more, it rises, and when it weighs less it falls.

An instrument used to measure wind speed is a Anemometer. The Anemometer first started out only having three cups but know it consists of either three or four cup devices. When the wind blows, each cup catches a certain amount of air that causes them to spin around. The Anemometer measures in miles per hour, kilometers per hour and knots.

Humidity is measured with a phychrometer. It has two bulbs, a dry one and a wet one with a rag. The wet bulb is used to measure how humid the air is and the dry one measures the temperature in the air. This is measured in MBAR.

A rain gauge is measures in inches and collects the amount of rain that has fallen in a certain area. It measures rain and how much of it has fallen.

A hydrometer is used to measure relative density or specific gravity of liquids. That is the ratio of the density of the liquid to the density of water. It is measured in grams.

Weather Summary for today:
Today started off with bright sunshine and a few clouds. By noon it was up to 70 F. The humidity wasn't very high today, which is always good for girls and their hair. I went to go lay out at about 3 in the afternoon and after being out there for only 15-20 minutes i already had a noticeable tanline. It was a gorgeous hot day and the wind added a nice cool breeze to it.

Weather Summary:
This morning I woke up to the rain pouring down on my window. It rained till about noon, and the it dried up a little bit until the next batch of rain came around. The storms are probably around Arkansas by now, cause there have been tornado warnings spotted in that area today. The high today was around 67 F and the low was 47 F. Not a big difference in temperature, probably because of the off and on rain throughout the day.

Today was a pretty hot day with a high near 80 F. It wasn't my favorite kind of weather once we had to run outside for cheer. It felt like the heat index was near 100 F. It was a clear day for the most part and there were high gusts of wind here and there thoughout the day. There has been storms issued for the weekend, so we should be expecting the humidity to rise until the storms arive.

Image found here.
An upper-level system has dropped from Canada to New York and New England. Snow has been falling from the skies in New York since Monday afternoon and will continue to fall until Wednesday. Six to Twelve inches of snow is expected to fall in the higher mountain areas. By Wednesday, temperatures should continue to rise as this will cause the snow to turn into a mix or freezing rain except in high elevations. This cold front will also bring a frost or mixture to many other states Wednesday morning on the northeastern coast.

This morning started out a bit chilly. Although I can't say I had much time to really examine the weather since of course it was a bit too early for me. You may have needed a jacket with the temperature at 46 F. Although as the day progressed, we reached a high of 69 F by lunchtime. Temperatures are decreasing as the day goes on. We had a humidity of 46% and the dewpoint was 46 F. The grass shouldnt be wet in the morning by looking at the dewpoint. The wind gust was 3.8 mph from the NW.
