帮出一套气体环流的案例题目---**Extracted Content:**
**Section 1 (Top):**
* Label: D
* Text (Left Diagram):
* 夜晚陆地降温快 (Night land cools quickly)
* 夜间海洋降温慢 (Night ocean cools slowly)
* 陆地 (Land)
* (冷源) (Cold source)
* 海洋 (Ocean)
* (热源) (Heat source)
* Text (Right):
* 陆风 (Land breeze)
* 夜晚山风 (Night mountain wind)
**Chart/Diagram Description (Top Diagram):**
* Type: Schematic diagram illustrating air circulation.
* Main Elements:
* Two regions labeled "陆地" (Land) and "海洋" (Ocean).
* Text below "陆地": "(冷源)" (Cold source).
* Text below "海洋": "(热源)" (Heat source).
* Horizontal arrow pointing from "陆地" to "海洋" near the bottom/middle level.
* Vertical arrow pointing downwards above "陆地".
* Vertical arrow pointing upwards above "海洋".
* Horizontal arrow pointing from above "海洋" towards above "陆地" (completing the circulation loop).
* The diagram depicts air sinking over the "冷源" (Land at night) and rising over the "热源" (Ocean at night), with surface flow from land to sea.
**Section 2 (Middle):**
* Text: 陆风 (Land breeze)
**Section 3 (Bottom):**
* Text (Left Diagram):
* 白天陆地增温快 (Day land heats up quickly)
* 白天海洋增温慢 (Day ocean heats up slowly)
* 陆地 (Land)
* (热源) (Heat source)
* 海洋 (Ocean)
* (冷源) (Cold source)
* Text (Right):
* 城市热岛效应 (Urban heat island effect)
* Text (Bottom Left):
* 海风 (Sea breeze)
**Chart/Diagram Description (Bottom Diagram):**
* Type: Schematic diagram illustrating air circulation.
* Main Elements:
* A sun symbol in the upper right corner, indicating daytime.
* Two regions labeled "陆地" (Land) and "海洋" (Ocean).
* Text below "陆地": "(热源)" (Heat source).
* Text below "海洋": "(冷源)" (Cold source).
* Horizontal arrow pointing from "海洋" to "陆地" near the bottom/middle level.
* Vertical arrow pointing upwards above "陆地".
* Vertical arrow pointing downwards from above "海洋".
* Horizontal arrow pointing from above "陆地" towards above "海洋" (completing the circulation loop).
* The diagram depicts air rising over the "热源" (Land during the day) and sinking over the "冷源" (Ocean during the day), with surface flow from sea to land.
**Other Notes:**
* The content is divided by dashed lines.
* A large handwritten "D" is present in the top right section.
* The document appears to be handwritten notes summarizing different local wind phenomena.
