A - Moist Tropical Climates are known for their high temperatures year round and for their largeamount of year round rain. 2. B - Dry Climates are characterized by little rain and a huge daily temperature range. Two subgroups, S - semiarid or steppe, and W - arid or desert, are used with the B climates.3. C - In Humid Middle Latitude Climates land/water differences play a large part. These climates have warm,dry summers and cool, wet winters.4. D - Continental Climates can be found in the interior regions of large land masses. Total precipitation is not very high and seasonal temperatures vary widely.5. E - Cold Climates describe this climate type perfectly. These climates are part of areas where permanent ice and tundra are always present. Only about four months of the year have above freezing temperatures.These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.a. Further subgroups are designated by a second, lower case letter which distinguish specific seasonal characteristics of temperature and precipitation.b. f - Moist with adequate precipitation in all months and no dry season. This letter usually accompanies the A, C, and D climates. c. m - Rainforest climate in spite of short, dry season in monsoon type cycle. This letter only applies to A climates.d. s - There is a dry season in the summer of the respective hemisphere (high-sun season).e. w - There is a dry season in the winter of the respective hemisphere (low-sun season).i. To further denote variations in climate, a third letter was added to the code.ii. a - Hot summers where the warmest month is over 22°C (72°F). These can be found in C and D climates. iii. b - Warm summer with the warmest month below 22°C (72°F). These can also be found in C and D climates.iv. c - Cool, short summers with less than four months over 10°C (50°F) in the C andD climates.v. d - Very cold winters with the coldest month below -38°C (-36°F) in the D climateonly.vi. h - Dry-hot with a mean annual temperature over 18°C (64°F) in B climates only.vii. k - Dry-cold with a mean annual temperature under 18°C (64°F) in B climates
