Isabela State University Cauayan City Campus Midyear Class 2022 August 9, 2022 - 5 pm August 10, 2022 - 3 pm August 11, 2022 – 1 pm August 12, 2022 – 2 pm August 13, 2022 – 2 pm SED SCI 328 Meteorology ACTIVITY 4 CLOUD FORMATION Objective
1.Take pictures of clouds you see for five straight days ( any time of the day ) and identify the type of these clouds. ( 10 pts ) *If possible, your pictures should capture these clouds clearly WITH YOU in that picture a) August 9, 2022 Type of cloud : Nimbostratus Why and How : Nimbostratus clouds form a thick, dark layer across the sky. They are often thick enough to blot out the sun. Like cumulonimbus clouds, they are associated with heavy precipitation, but, unlike cumulonimbus, you can’t pick out individual nimbostratus clouds. b) August 10, 2022 Type of cloud : Altostratus Why and How : These clouds form a white or gray layer that blankets the sky at mid-level. There are usually no patches of blue sky when these clouds appear, but the sun is often visible as a dimly lit disk behind the clouds (although no shadows appear on the ground). c) August 11, 2022 Type of cloud : Cumulus Why and How : The stereotypical puffy cloud you probably drew a lot of when you were a kid, cumulus clouds are dense individual clouds that are bright white on top and gray underneath. They typically appear earlier in the day when it’s sunny. d) August 12, 2022 Type of cloud : Stratocumulus Why and How : Stratocumulus clouds are somewhat similar to cumulus clouds but are flatter, thicker, and darker. There is less blue sky between the clouds, and the weather will appear more cloudy than sunny. e) August 13, 2022 Type of cloud : Nimbostratus Why and How : Nimbostratus clouds form a thick, dark layer across the sky. They are often thick enough to blot out the sun. Like cumulonimbus clouds, they are associated with heavy precipitation, but, unlike cumulonimbus, you can’t pick out individual nimbostratus clouds. 2.Describe these clouds and indicate according to the kind of weather you might expect when you see them in the sky. (10 pts )
Color: Dark gray Shape: Large thick layer Weather: Steady rain or snow Nimbostratus clouds form a thick, dark layer across the sky. They are often thick enough to blot out the sun. Like cumulonimbus clouds, they are associated with heavy precipitation, but, unlike cumulonimbus, you can’t pick out individual nimbostratus clouds. 3.How are theses clouds named and classified? ( 5 pts ) The easiest way to tell different types of clouds apart is by looking at their shape, height, and weather. There are three main different cloud shapes, and they all look quite different from one another, so identifying the shape will help you narrow down your options easily before moving onto other steps and identifiers to determine which specific cloud type you’re looking at. HEIGHT: High-level, Mid-level, Low-level Puffy (Cumulo-form) Thick layer (Strato-form) Wispy (Cirro-form) Cumulus Altocumulus Stratocumulus Cumulonimbus Cirrocumulus Stratus Altostratus Nimbostratus Cirrus Cirrostratus 4.Select a published article on recent findings or any meteorological innovations about clouds. Summarize the article. ( 10 pts ) “Cloud seeding might not be as promising as drought-troubled states hope” Forecasters at the National Oceanic and Atmospheric Administration issued their U.S. spring outlook on March 17, 2022, and their top concern was worsening drought in the West and southern Plains. Several western states have experimented with cloud seeding to try to increase precipitation, but how well does that actually work? Atmospheric scientist William Cotton explains. On mountain peaks scattered across Colorado, machines are set up to fire chemicals into the clouds in attempts to generate snow. The process is called cloud seeding, and as global temperatures rise, more countries and drought-troubled states are using it in sometimes desperate efforts to modify the weather. But cloud seeding isn’t as simple as it sounds, and it might not be as promising as people wish. Cloud seeding experiments that produce snow or rain require the right kind of clouds with enough moisture, and the right temperature and wind conditions. The percentage increases in precipitation are small, and it’s difficult to tell when snow or rain fell naturally and when it was triggered by seeding.
The modern age of weather modification began in the 1940s in Schenectady, New York. The results of about 70 years of research into the effectiveness of cloud seeding are mixed. Most scientific studies aimed at evaluating the effects of seeding cumulus clouds have shown little to no effect. However, the results of seeding wintertime orographic clouds – clouds that form as air rises over a mountain – have shown increases in precipitation. 5.Cite your references. ( 5 pts. ) References
