Heat's effect on the wind cycle is most easily observed near the sea. During the day, the ocean absorbs heat from the surface, keeping the air above it cooler than above the land. When the warm air rises from the shore, the cooler air from the ocean blows in to take its place. At night, the land cools quickly, while the ocean radiates the heat it absorbed, keeping the air above warm. This reverses the effect, causing the air offshore to rise and creating a breeze from the land. Uneven heating can also occur due geographical features. A mountainside exposed to the sun will warm more than a shadowed valley below it, creating a wind that blows uphill during the day and downhill at night.
The same principle is responsible for global wind patterns. The polar regions receive less solar radiation than areas near the equator, resulting in a global shift in temperature according to latitude. This, along with differences in temperature and density in various layers of the atmosphere, creates global wind patterns like the jet stream that help drive weather systems.

Answer:
Langerhan's cells
Explanation:
The Langerhan's cells arise from the bone marrow and migrate to the epidermis. The Langerhan's cells are the body's first line of defense and play a significant role in antigen presentation. They need special stains to be visualized and are primarily found in the stratum spinosum. These are the mesenchymal origin obtained from CD34 positive stem cells of bone marrow and are part of the mononuclear phagocytic system.
