In addition to the barometer graph (see 9.6 Using Barometer profile),
Suunto Ambit3 Peak has two weather indicators: weather trend and storm
alarm.
The weather trend indicator is displayed as a view in TIME mode,
providing you a quick way to check weather changes.
The weather trend indicator is comprised of two lines forming an arrow.
Each line represents a 3-hour period. A change in barometric pressure
greater than 2 hPa / 0.59 inHg over three hours triggers a change the
direction of the arrow. For example:
pressure dropping heavily over the last six hours
pressure was steady, but rising heavily over the last three hours
