A typical weather house has two doors side by side. The left side has a girl or woman, the right side a boy or man. The female figure comes out of the house when the weather is sunny and dry, while the male (often carrying an umbrella) comes out to indicate rain.
Around 1810 the wheel barometer, which could be read from a great distance, became the first practical and commercial instrument favoured by farmers and the educated classes in the UK. The face of the barometer was circular with a simple dial pointing to an easily readable scale: "Rain - Change - Dry" with the "Change" at the top centre of the ...
Barometer for measuring atmospheric pressure; Hygrometer for measuring humidity; Anemometer for measuring wind speed; Pyranometer for measuring solar radiation; Rain gauge for measuring liquid precipitation over a set period of time; Wind sock for measuring general wind speed and wind direction
The experiment uses a simple barometer to measure the pressure of air, filling it with mercury up until 75% of the tube. Any air bubbles in the tube must be removed by inverting several times. After that, a clean mercury is filled once again until the tube is completely full. The barometer is then placed inverted on the dish full of mercury.
Atmospheric pressure, also known as air pressure or barometric pressure (after the barometer), is the pressure within the atmosphere of Earth.The standard atmosphere (symbol: atm) is a unit of pressure defined as 101,325 Pa (1,013.25 hPa), which is equivalent to 1,013.25 millibars, [1] 760 mm Hg, 29.9212 inches Hg, or 14.696 psi.

A line drawing is the most direct means of expression. This type of drawing without shading or lightness, is usually the first to be attempted by an artist.It may be somewhat limited in effect, yet it conveys dimension, movement, structure and mood; it can also suggest texture to some extent.
Contour drawing – Chiaroscuro – using strong contrasts between light and dark to achieve a sense of volume in modeling three-dimensional objects such as the human body. Gesture Drawing - loose drawing or sketching with the wrists moving, to create a sense of naturalism of the line or shape, as opposed to geometric or mechanical drawing ...
Above-ground casing of a piezometer Symbol used in drawings. A piezometer is either a device used to measure liquid pressure in a system by measuring the height to which a column of the liquid rises against gravity, or a device which measures the pressure (more precisely, the piezometric head) of groundwater [32] at a specific point.
