The effects of the rainy season vary from one region to another. Understanding how rain works in your area will help you adapt to your unique environment. Here are some important things to consider during this season:
Tropical wet climates
The term “rainy season” refers to the rainy period, which occurs during the summer months. During the winter, the temperature varies little and is comparatively cold, although it is often humid. Tropical wet climates are usually characterized by two distinct seasons, the wet and the dry. This characteristic is caused by the shift in ocean currents and wind patterns. However, some regions experience more rain in summer than others.
In the tropics, the rainy season lasts from June to October in the northern hemisphere and from December to April in the southern hemisphere. The warm tropical air masses and the higher sun’s heat result in rain. Although temperatures remain high during the daytime, they drop dramatically at night. Rainfall may range from ten to fifty inches per year. It is important to note that rainy seasons can be particularly long, so make sure you pack appropriately for the weather.
Monsoon rains in India account for nearly 80% of the country’s rainfall. The rainy season in India is crucial because agriculture makes up about 25% of the country’s GDP and employs 70% of the population. Agricultural activities in India depend on the rainy season to produce crops like rice, cotton, oilseeds, and coarse grains. During the rainy season, a delay of a few days can have devastating effects on the economy. The monsoon also brings floods to certain parts of Bangladesh and certain regions of India.
In the past, monsoon rains were believed to be caused by the temperature of the land, but scientists have discovered that they are actually a planetary phenomenon. The Intertropical Convergence Zone migrates every year across the globe. Because of its varying temperatures, its limits vary, influencing the duration and strength of the rainy season. The high Tibetan Plateau, for example, influences the rainy season in South Asia.
In the U.S., extreme precipitation has been increasing for more than three decades. This index measures the number of two-day precipitation events exceeding the threshold of a 5-year recurrence. The most extreme precipitation events occur in the Midwest and northeast, while the Southwest has remained fairly stable. Precipitation levels have remained above normal during the past three decades. Precipitation levels are rising for some regions but remain lower for others.
While the global average is rising, extreme precipitation is increasing as well. According to climate models, half of the extra precipitation will fall in the six wettest days of the year. Increasing extremes in precipitation mean a longer and more severe rainy season. In the U.S., extreme rainfall from landfalling tropical cyclones has increased more than 100 percent since 1981. And this trend is not limited to rainy season.
Impact on life adaptations
The impact of the rainy season on life adaptations is not new. Seasonal rains account for 80 percent of the total annual rainfall, and climate change is making the season more unpredictable. The region is already planning for an increase in cyclones and deadly heat. The new monsoon has disproportionately affected vulnerable people. These people are the least equipped to deal with the economic costs of lost crops and homes. As a result, the effects of climate change are being felt even more acutely.
Rainfall occurs during the warmest part of the day and falls in the early evening. The rainy season generally improves air quality, especially in regions with monsoon season. It increases vegetation, leading to increased crop yields late in the season. It also causes rivers to overflow their banks. In addition, the rainfall balances the pH of the water, making it softer. During the rainy season, some animals retreat to higher ground, while others reproduce. In some regions, this leads to food shortages and malaria.
Traveling during the rainy season
Many places have their own rainy season. When traveling during this time, you can expect fewer crowds, cheaper airfare, and more intimate experiences. However, you will also have to contend with the inclement weather. Here are some tips for traveling during the rainy season:
Safety is of prime concern while traveling during the rainy season. Because the weather changes constantly, some places are closed to the public. Changing weather conditions may make travelers ill, so be sure to pack appropriate rain gear. If you’re traveling during the rainy season, you should also pack some essential medications in case of illness. A good idea is to book your accommodations well ahead of time so you can get the best rates.
