Three types of rain

• Convectional rain (stijgingsregen)
• Frontal rain (Frontale regen)
• Relief rain (stuwingsregen)

Convectional rain (stijgingsregen)

Hot air rises. The higher, the colder. The water vapour in the rising air starts to condense. Which leads to rain we call convectional rainfall.

Where does rain occur?

Frontal rain (Frontale regen)

At temperate latitudes (gematigde breedte), warm air from low latitudes clash against cold air from polar regions, the warm air is forced to rise and frontal rain forms.

Relief rain (stuwingsregen)

When air is blown against mountains, the air is forced to rise, cools down and condenses. Leading to rainfall. This rain is called relief rainfall. On the other side of the mountains, it is dry, because the clouds have already emptied themselves of rain.
