The correct answer is Option 4. Explanation & Key Takeaways: Chinook winds: • It is a strong, dry, warm local wind that blows in the cold winter months of the regions located to the east of the Rocky Mountains. • They can bring quick temperature changes. • Hence, statement 1 and 2 are correct. • It blows from the Pacific Ocean in the northwest region of North America toward the Rocky Mountain range. Hence, statement 3 and 4 are incorrect. • The air mass cools as it climbs the mountains, bringing rain or snow to the peaks. • It dries after releasing its moisture in the mountains and warms as it moves down the eastern side of the mountains. • Wind warms rapidly and gradually becomes warmer and drier than the original air mass coming from over the Pacific Ocean. • When it changes direction toward the west or southwest, its speed rapidly increases. • Its speed can reach up to 128 km/h. Snow eaters: • When these warm, dry, fast-moving winds pass over snow-covered areas, the snow often vaporizes before it has a chance to melt. • These winds can easily vaporize a foot of snow within hours. • That's why these winds are often known as the "snow eaters." Note: • Rhine river is in Germany. • Alps mountain ranges are present in Europe. Related Concepts: • These winds are named after the Chinook Native Americans who lived in the coastal regions of Washington and Oregon near the Columbia River. • These winds are known with different names in various parts of the world that includes: • Central Asia: Afganet, • Andes of South America: Puelche, • Southern California: Santa Ana winds.
