1. START Warm air blows

2. START Warm air blows From the west Off the Atlantic Ocean

3. START Warm air blows From the west Off the Atlantic Ocean Carrying a lot of moisture The warm air is forced

4. START Warm air blows From the west Off the Atlantic Ocean Carrying a lot of moisture The warm air is forced To rise over the Atlas Mountains of Morocco And in so doing the air cools.

5. START Warm air blows From the west Off the Atlantic Ocean Carrying a lot of moisture The warm air is forced To rise over the Atlas Mountains of Morocco And in so doing the air cools. The cooling causes moisture in the air To condense

6. START Warm air blows From the west Off the Atlantic Ocean Carrying a lot of moisture The warm air is forced To rise over the Atlas Mountains of Morocco And in so doing the air cools. The cooling causes moisture in the air To condense Giving clouds As the air rises higher

7. START Warm air blows From the west Off the Atlantic Ocean Carrying a lot of moisture The warm air is forced To rise over the Atlas Mountains of Morocco And in so doing the air cools. The cooling causes moisture in the air To condense Giving clouds As the air rises higher There is heavy rain over the Atlas Mountains And even snow

8. START Warm air blows From the west Off the Atlantic Ocean Carrying a lot of moisture The warm air is forced To rise over the Atlas Mountains of Morocco And in so doing the air cools. The cooling causes moisture in the air To condense Giving clouds As the air rises higher There is heavy rain over the Atlas Mountains And even snow In winter This is called RELIEF RAINFALL

10. But then the air sinks After passing the mountains

11. But then the air sinks After passing the mountains And as the air sinks it warms So any moisture in the air

12. But then the air sinks After passing the mountains And as the air sinks it warms So any moisture in the air Evaporates Making the clouds disappear

13. But then the air sinks After passing the mountains And as the air sinks it warms So any moisture in the air Evaporates Making the clouds disappear Leaving clear blue skies And permanently dry weather

14. But then the air sinks After passing the mountains And as the air sinks it warms So any moisture in the air Evaporates Making the clouds disappear Leaving clear blue skies And permanently dry weather In the arid Sahara Desert. This area in Libya and Algeria

15. But then the air sinks After passing the mountains And as the air sinks it warms So any moisture in the air Evaporates Making the clouds disappear Leaving clear blue skies And permanently dry weather In the arid Sahara Desert. This area in Libya and Algeria Of really dry conditions On the leeward side

This area in Libya and Algeria Of really dry conditions On the leeward side (Or sheltered side) of the mountains Is called a RAIN SHADOW area
