Final answer:

Winds are created predominantly by the process of convection, where warm air rises and cooler air moves in, a process that is largely driven by the uneven heating of the Earth's surface by the Sun. The phase changes of water also contribute greatly to wind formation and weather systems, with energy transferred via evaporation and condensation. Conduction and radiation are other heat transfer methods affecting climate differently.

Step-by-step explanation:

Winds are created through the process of convection, which involves the movement of air as the atmosphere tries to equalize global temperatures. The Sun's energy, which is the result of nuclear reactions within the Sun, reaches the Earth and heats its surface differently at various locations. During convection, warm air rises, and cooler air moves in to replace it, creating wind. The uneven heating of the Earth's surface by sunlight and the rotation of the Earth also contribute to varying wind patterns around the globe.

This process is amplified by the phase changes of water. As water evaporates from the oceans, heat is removed, and when the water vapor condenses in clouds, heat is released into the atmosphere. This energy release causes the air to expand, rise, and cool, which leads to further condensation and powerful weather systems like thunderstorms and hurricanes, driven by positive feedback mechanisms.

Other methods of heat transfer such as conduction and radiation also play roles in the Earth's climate system but in different contexts. Conduction is the transfer of energy through collisions between atoms or molecules, as experienced when a metal spoon handle heats up in hot coffee. Radiation involves the emission of energy in the form of photons from a hot material, such as the warmth felt from a fire mostly through infrared radiation.
