monsoon
Definition
A monsoon is a seasonal wind system that brings alternating periods of wet and dry seasons to a region. Monsoons occur in many parts of the world, including India, Southeast Asia, and Australia.
Monsoons are caused by the difference in temperature between the land and the ocean. In the summer, the land heats up faster than the ocean. This causes the air above the land to rise, creating an area of low pressure. The air above the ocean is then drawn towards the land, bringing with it moisture from the ocean.
When the moisture-laden air reaches the land, it rises and cools. This causes the water vapour to condense and form clouds. The clouds then release the water as rain, which falls on the land.
The amount of rain that falls during a monsoon season can vary greatly. In some areas, the monsoon can bring several feet of rain, while in other areas, it may only bring a few inches. The amount of rain that falls also depends on the location of the monsoon system. Monsoon systems that form over the Indian Ocean tend to be more intense than monsoon systems that form over the Pacific Ocean.
Monsoons are an important source of water for many parts of the world. They help to irrigate crops and provide drinking water for people and animals. However, monsoons can also be destructive. Heavy rains can cause flooding and mudslides, which can damage property and displace people.
How can the word be used?
The monsoon season is a time of great flooding in some parts of the world.
Different forms of the word
Noun: A seasonal wind system that reverses direction between summer and winter.
Adjective: Relating to or characteristic of a monsoon.
Verb: To cause a monsoon.
Etymology
The word "monsoon" comes from the Arabic word "mausim," which means "season." The word "mausim" was borrowed into Portuguese as "monção," and then into English as "monsoon.".
The word "monsoon" was first used in English in the 16th century to describe the seasonal winds in the Indian subcontinent. The monsoon winds bring much-needed rain to the Indian subcontinent in the summer, but they can also cause flooding and other damage.

AQA Science Exam Question and Answer
Question:
What is a monsoon and how does it impact weather patterns in specific regions? Provide an example of a region that experiences monsoons and explain the changes in weather and climate associated with the monsoon phenomenon.
Answer:
A monsoon is a seasonal wind pattern that brings about distinct changes in weather conditions, particularly in regions near large bodies of water. Monsoons are characterised by their alternating wet and dry phases, and they play a crucial role in shaping the climate of certain areas.
One notable example of a region experiencing monsoons is Southeast Asia, particularly countries like India and Bangladesh. In these regions, the monsoon season is divided into two phases: the wet monsoon and the dry monsoon. During the wet monsoon, warm, moisture-laden air from the Indian Ocean flows onto the land, bringing heavy rainfall. This can lead to flooding but also ensures a water supply for agriculture. Conversely, the dry monsoon occurs when the winds shift, carrying cooler, drier air from the land to the sea, resulting in a reduction in rainfall.
The monsoon phenomenon is critical for agriculture and the overall ecosystem in these regions. Crops depend on the ample water supply brought by the wet monsoon, while the dry phase allows the soil to be cultivated and prepared for planting.
