Essay on Rainy Season
A rainy season is traditionally defined as a time of year when most rain falls. In temperate countries, this is usually autumn and spring, although the timing varies somewhat with latitude and climate. In the tropics, two rainy seasons occur, one in the early part of the year and the other in the late part of the year. In many tropical countries, these two seasons are referred to as “the dry season” and “the rainy season”, respectively. In Australia, a statistical division known as a climatological winter (traditionally June–August), which corresponds to the cool part of other countries’ wet summers and warm winters, is recognized in some places for recording purposes. A dry season is defined as a time when most rain falls.
The conventional terms “monsoon” and “anti-monsoon” are used to refer to the different phases of the monsoonal cycle.
In the tropical regions, a monsoon season lasts from one to four months, while in the temperate and arctic, a winter season lasts for six months. In some southern areas with a short summer wet season, the dry season is limited to one month, resulting in a wet and dry year. In areas with longer summer rainy seasons and shorter winter dry seasons, “lengthening” of the wet season or “shortening” of the dry season can occur. In areas with longer summer rainy seasons, “shortening” of the wet season or “shortening” of the dry season can occur. The longest-lasting monsoon systems are found around Australia; these may persist for more than two years from March to November.
Monsoons occur in association with a wide range of climate patterns, and are not limited to the tropics. Monsoons can exhibit a sizable temperature change over their durations, and are responsible for large-scale air masses that dominate much of the seasonal weather over large areas of Asia and North America.
The term “monsoon” originally comes from the Arabic word mawsim which refers to the changing or blowing season. Many different historical records confirm that the rainy season has been an important part of human society for thousands of years. Early monsoon rains increase agricultural productivity in most areas, and enable semi-arid regions to support crops. In southwestern and eastern Asia, monsoon rains are a seasonal staple that falls primarily during the late-summer or early-autumn period. In a typical example from India, monsoon rains begin in June, provide relief from the heat of the summer, and often last until September or later. Tropical areas have two rainy seasons: the first one is called “the little monsoon”, followed by the main “monsoon season”, but sometimes it can rain during both seasons.
The term “monsoon” is also used to refer to seasonal changes in atmospheric circulation in other parts of Asia. For example, in places such as northern China and northern India, the wind direction and speed actually changes through the seasons. In these areas, there is often a change from a dry to wet season during which rain falls more frequently.
Rain is an important part of the water cycle and is responsible for depositing most of Earth’s, and oceans, precipitation. Monsoonal rains make up anywhere between 40 and 70 percent of the annual rainfall in some parts of the world. The intensity and frequency of monsoon rains vary widely with location, from as little as one inch per month in parts of Africa to over thirty inches per month in a few regions in Asia. Monsoon storms cause heavy flooding when they reach the deltas of the major river systems such as the Ganges, Indus, Yellow River, Pearl River and others.
In rainy season, animals have to leave their original habitats and look for shelter. This can result in conflict between animals of different species, as well as humans who also need to find shelter in the rain. In places such as India, chinkara and houbara bustards have been known to come into villages looking for food and getting into fights with cows which can leave casualties on both sides. In places such as Brazil, cougars have been known to attack people when they get too close, so people have to be careful where they go when it is raining.
Historically the rainy season has been a time of large-scale migration. The wet season has traditionally been associated with the death of millions of people, due to disease and malnutrition. Today about half the world’s population lives in areas where the rainy season lasts for six or more months. Because the primary food is grown during this time period, many people are at risk for malnutrition and starvation.
In regions such as Java and Bali there are reports of negative mental health effects on individuals as well as families due to prolonged droughts that lead to lack of food and water. During these droughts it is common for people to leave their homes in search of alternatives such as going into town or taking up a job. The stress associated with these movements is not only related to loss of a familiar place, but it can also be about losing social support. The movement in and out of urban areas and the deterioration of local neighborhoods can result in a decrease in the quality of life.
Monsoons are an important part of all ecosystems because they provide water for the plants, animals and people that live there. Monsoons have a significant impact on food availability, particularly for low-income populations that depend on agriculture for their daily meals. Monsoons also have an impact on the transmission of disease in local populations. For example, floods can spread diseases such as dengue fever and malaria, which can then result in increased infections of those diseases in the people and animals affected.
Monsoon season is the primary reason for vacation travel to many destinations across the world. From places like Thailand to Brazil, travelers make a trip during these seasons to escape cities like Bangkok and Rio de Janeiro that see heavy traffic during monsoons. For some areas, these seasons are considered more important than Christmas or summer vacation for bringing greater tourist revenue to destinations. The massive population growth across Asia has significantly improved tourism during monsoon season.
Rain has a dramatic effect on agriculture. In many areas, farmers rely on the rain to grow their plants and will anxiously await the season. With the monsoon comes a great need for crops that can withstand either too much or too little water. The C4 plants are able to grow with reasonable amounts of water and have more stable amounts of photosynthesis. Their growth is very dependent on water, so they will often sprout in the rainy season as they need more water than others.
The monsoon plays a crucial role in the lives of many people around the world. From farmers and businessmen to tourists, everyone is affected by this seasonal weather phenomenon. There are both positive and negative effects on human life in the areas affected by these seasons. They are an important part of many ecosystems as well, including helping some animals to migrate from one location to another. It takes several months to go through one cycle of a monsoon, but no matter what side of this seasonal weather phenomenon humans stand, it is always present in their daily lives.
