Types of precipitation

Goal:

Understand how the 3 

types of precipitation

are formed.

What are the steps that lead to precipitation? Show them in a drawing

3 causes for rising air:  

1. Air is pushed up by a mountain               relief rainfall

2. Cold and warm air meet                             frontal rainfall

3. Warm/hot air is rising                                   convectional rainfall

1. Relief rainfall 

windward side

wet air from sea

rain shadow

leeward side

dry air

2. Frontal rainfall

Warm air from the equator

meets cold air from the pole

Cold air is heavy and pushes

up the warm air.

Cools down-> rain

3. Convectional

rainfall

Warm air rises

Cools down               Rain!

Around the equator, but also

hot summer days-> afternoon

Van links naar rechts 

Which type is the left one?

1. relief rainfall
2. convectional rainfall
3. condensation
4. frontal rainfall

Which type is the middle one?

1. relief rainfall
2. convectional rainfall
3. condensation
4. frontal rainfall

Which type is the right one?

1. relief rainfall
2. convectional rainfall
3. condensation
4. frontal rainfall

Which one do we have in the Netherlands most often?
Also explain why.

Frontale neerslag

Warme en koude lucht botsen tegen elkaar -> koude lucht is zwaar en de warme lucht is gedwongen op te stijgen. Als warme lucht opstijgt, koelt hij af. Hierdoor ontstaan er wolken en gaat het regenen.

Frontale regen komt veel veel in Nederland. Wij liggen aan zee en  hebben geen bergen. Wel komt de wind bijna altijd uit het zuidwesten.

Een front = plek waar warme en koude lucht elkaar tegenkomen.

Show a place where we have relief rainfall.

Andesgebergte -> stuwingsneerslag

Characteristics of areas
with a lot of convectional
rainfall.

Tropisch regenwoud

Goal: understand formation of 3 types of rainfall
