readout area will also

indicate if the pressure

is FALLING, STEADY, or

RISING.

FORECAST: future forecast icon

The display console features a weather forecast icon which gives you

the predicted weather forecast for the next 12 to 24 hours based on

an advanced algorithm that observes the changes in barometric

pressure and temperature. The FORECAST icon will then predict the

future (next 12 to 24 hours) weather forecast. This weather station

will provide the most accurate forecast that a single station weather

instrument can provide.

FORECAST: 14 day learning mode

This weather station has a patented “fourteen day learning mode”

calibration process. During this learning mode the weather station

will make altitude calculations that may affect the accuracy of the

forecast. Once the 14 day learning mode process is complete, the

learning mode icon will disappear and the weather forecast should

be ready for superior operation.

Atmospheric Pressure is defined as the pressure at any location on

the Earth, caused by the weight of the column of air above it. At sea

level, atmospheric pressure has an average value of one atmosphere

and gradually decreases as altitude increases. Also called

barometric pressure.

The weight of the atmosphere that envelopes Earth exerts pressure

on all points of the planet's surface. Meteorologists use barometers

to measure this atmospheric pressure (also called barometric

pressure). At sea level the atmospheric pressure is approximately 1

kilogram per square centimeter (14.7 pounds per square inch),

which will cause a column of mercury in a mercury barometer to rise

760 millimeters (30.4 inches). Variations in the atmospheric pressure

greatly affect the weather. Low pressure generally brings rain. In

areas of low air pressure, the air is less dense and relatively warm,

which causes it to rise. The expanding and rising air naturally cools,

and the water vapor in the air condenses, forming clouds and the

drops that fall as rain. In high pressure areas, the air is dense and

relatively cool, which causes it to sink. The water vapor in the sinking

air doesnʼt condense, resulting in clear skies.
