Displaying Weather Variables

3. Continue pressing WxCEN to scroll through all the barometric pressure-related Weather

Center screens, which include:

• Barometric Pressure Change Per 24 hours — Displays the difference between the

barometric pressure currently recorded and the barometric pressure recorded at the same

time yesterday. (Updated on the hour.)

• Maximum Barometric Pressure — Displays the highest barometric pressure reading

for the day and the time the measurement was recorded.

• Minimum Barometric Pressure — Displays the lowest barometric pressure reading for

the day and the time the measurement was recorded.

• Altimeter Setting — Displays the barometric pressure that would display if “ALT SET-

TING” was selected in Screen 11: Barometric Reduction Setting. The barometric pres-

sure reading and the altimeter setting reading will be the same if the altimeter setting

was selected. See “Screen 11: Barometric Reduction Setting” on page 12 for more infor-

mation.

• Absolute Pressure — Displays the barometric pressure that would display if “NONE”

was selected in Screen 11: Barometric Reduction Setting. The barometric pressure read-

ing and the absolute pressure reading will be the same if none was selected. See “Screen

11: Barometric Reduction Setting” on page 12 for more information.

• Barometric Pressure Trend — Describes the current barometric trend and the numeric

change in the barometric pressure over the last three hours. The barometric pressure

trend listed in the Weather Center corresponds to the pressure trend arrows displayed

next to the barometric pressure variable. The trends are:

• Bar Rising Rapidly — Refers to a rise in pressure greater than or equal to 0.06'' (2

hPa) over the last three hours.

• Bar Rising Slowly — Refers to a rise in pressure greater than or equal to 0.02'' (0.7

hPa) but less than 0.06'' (2 hPa) over the last three hours.

• Bar Steady —Refers to no change or a change of less than

0.02'' (0.7 hPa) either rising or falling over the last three hours.

• Bar Falling Slowly — Refers to a fall in pressure greater than or equal to 0.02'' (0.7

hPa) but less than 0.06'' (2 hPa) over the last three hours.

• Bar Falling Rapidly — Refers to a fall in pressure greater than or equal to 0.06'' (2

hPa) over the last three hours.

Pressure Trend

The pressure trend arrow indicates the current barometric trend, measured over

the last three hours. The pressure trend is updated every 15 minutes. The

pressure trend requires three hours of data in order to be calculated so it won’t

display right away on a new station. The pressure trend is indicated on the

console screen, as long as the required data is available.
