In forecast discussions you will come across the terms positive, neutrally and negatively tilted trough. When a trough is positive or neutrally tilted it is usually not referenced as such. However, when it becomes negatively tilted it will be referenced as such. The tilt of a trough is the angle the trough axis makes with lines of longitude. 1, record 1, English, - tilted%20trough

Strong upper-level disturbances form negatively-tilted troughs. Sometimes you hear television meteorologists refer to a negative-tilt trough and how it is going to spawn an intense storm. A strong upper-level disturbance can turn a routine positive-tilt trough into massive, storm-spawning negative-tilt trough.... a positive tilt trough's axis is oriented from northeast to southwest while a negative tilt trough's axis is oriented from northwest to southeast. 1, record 3, English, - positive%20tilted%20trough
