Introduction:
Winter, spring, summer, and fall/harvest
time are four seasons that many people experience. Regardless, those four do
not reach out to every corner of the globe. Because of the tropics' centre
region, that zone only has two seasons: wet and dry. Meanwhile, areas near the
Indian Ocean experience three distinct seasons: winter, summer, and storm.
Bangladesh divides these three seasons into six for a variety of reasons,
including agribusiness, business, and social convention: Summer (grisma), rainy
season (barsa), autumn (Sharat), late autumn (Hemanta), winter (Shith), and
spring are all Bengali terms (Basanta). We'll talk about the six seasons and
why Bangladesh has six instead of four.
SIX SEASONS OF BANGLADESH
Bangladesh has six distinct seasons. The
seasons include summer, rainy season, autumn, late fall, winter, and spring. A
season is made up of two months. Each season has its distinct characteristics.
In a season, people also have mixed feelings. In its orbit, the earth goes
around the sun. Because of the earth's yearly motion, the seasons vary here.
The country is rightfully referred to as a natural playground. Seasons have an
essential function in nature. Every two months, the natural environment here
shifts. A season is a term for such a transition. People's emotions change with
the seasons. They forgot about the boredom of life and went about their
everyday tasks in a fresh manner.
1. SUMMER
According to the Bengali calendar, the
first two months of the year, the summer season, Boishakh and Jaistha. The sun
got hotter, the water dried up, and many rivers lost their natural navigability
and cracked on the ground. Mango, jackfruit, litchi, and other seasonal fruits
can be found on the tree.
It occurs between March and April
throughout the spring and summer. Because these are the hottest months of the
year, it follows the winter season. The weather remains hot and humid
throughout most of April until the monsoon arrives in June or July, when it
begins to rain practically every day for days on end. Due to the harsh weather
conditions, most visitors avoid visiting Bangladesh during this period.
Summer is followed by the rainy season.
It's the second season of the show. The rainy months are 'ASHAR' and 'SRAVAN.'
Occasionally, it pours heavily. Occasionally, cats and dogs, as well as little
drips. This season, Bangladesh's major two crops, rich and jote, flourish.
According to the Bengali calendar, the
rainy season begins after summer. The torrential rains and peacocks at the
moment wiped away all of summer's warmth. The roads are a muddy mess. Nature
takes on new dimensions due to the profusion of river ditches. The rainy season
occurs in the months of Asher and Saban. The rivers and canal bills are
overflowing at this time.
Strong winds from the northeast usually
arrive in September or October, bringing rain clouds that endure for around ten
weeks. This can deliver more than half of Bangladesh's yearly rainfall,
resulting in severe floods in many locations.
Because the population is primarily rural,
most people lack insurance and rely on their working fields to support
themselves. When the crops are too wet to work through, we see a lot of
malnutrition because children can't receive sufficient nutrients from food if
it isn't prepared correctly. Malaria is also a significant health risk at this
time of year since mosquitoes increase and become quite aggressive when it
rains excessively.
Autumn arrives after the rain. The months
of the season are 'BHADRA' and 'ARSHIN.' There isn't as much rain as there used
to be. The sky has a rich blue colour, and flowers blossom during this time of
year. The number of days and nights is about equal. Autumn coincides with
Bhadra and Ashwin's month. It is regarded as the third of the six seasons. The
moths are photographed at this time.
Autumn is a great time for activities such
as fishing, soccer, and cricket. It's also the season for getting together with
friends for picnics and barbeques. In the evenings, the air is cold, although
it is still warm. With excellent local apples, pears, peanuts, and onion corn
soup, fall delivers many new cuisine options (shorgo shattah).
It's no surprise that now is a popular
season to visit Bangladesh. Foodies would consider themselves fortunate to be
able to get their hands on these delectable treats as they wander along
Bangladeshi alleyways dotted with fruit vendors and noodle stalls enticing
taste buds from every turn.
The autumn transitions to the late-autumn
period. 'KARTIC' and 'AGRAHAYAN' are the late-autumn months. It's dew season,
and the farmers appear in good spirits. They are occupied with harvesting the
Nabanna. Autumn is an excellent time of year. Nature provides a variety of
perspectives. It's neither hot nor cold, yet it's pretty pleasant. Late autumn
enhances the beauty of the natural world and its surroundings. Colourful birds
and butterflies may be spotted in the trees on bright days. The fields begin to
become a golden colour throughout the season as the crops mature. A rice disciple
gradually develops a gold colour. The view in rural Bengal changes when the
golden colour turns velvety all around it.
A rice swings in the fields disciple! Late
autumn is more mysterious to everyone's eyes because of the cold mornings, raw
gold sunshine, dusk-filled rainy nights, and dazzling night sinking in the
cloudless sky. Our nature lover was fascinated by the vast beauty of Bengal.
The gentle sunlight of late October reaches everyone. Late autumn is viewed
differently by the poet. In the night sky, numerous stars can be observed. On
the vast horizon, there was no sign of a dotted cloud. Throughout the night,
the stars glitter. Moonlight from the moon's body falls into the world at the
exact moment. At night, the scorching winds and soft light flashed.
The winter comes after the late fall. The
winter months are referred to as 'POUSH' and 'MAGH.'. Winter appears bleak. The
season is known as tuen, as the days are shorter and the nights are longer.
It's a foggy season.
These two months, Paus and Magh, are formed
of winter. Palm juice was used to produce several pitha and paiyesh throughout
the winter. Picnics are regarded as desirable and appropriate throughout the
winter months. The winter season lasts from December through February on average.
Winter begins with foggy, chilly days and frigid nights, but as the days grow
longer, it gradually warms up until summer, when it is the warmest time of the
year.
During this season, northward-bound winds
(often called "Boat wind") blow into our region, bringing warmer
temperatures and more humidity. These winds may produce dense fog over our
rivers and coastal areas, particularly in the Chittagong region, where
visibility can be reduced to less than a few meters at times, posing serious
traffic challenges.
The most lovely season is spring. The films
' FALGOON highlights this season' and 'CHAITRA.' It's known as the king.
Shootout with new leaves. Trees and plants provide a lovely appearance. Flowers
blossom, filling the air with sweet scents. The cycle of six seasons moves
because there is a delight in nature everywhere. Each season has its own set of
influences on the Bangladeshi people. In our country, we are fortunate to have
six seasons.
This spring will always be a season of
beauty and delight. It occurs between winter and summer and is the last of the
seasons. It appears throughout the Bengali months of 'Phalgun' and 'Chaitra.'
It is the most beautiful, lovely, and pleasant of all the seasons. Spring is
known as the 'Rituraj' because of its sweet-scented flowers, birds singing, and
mild wind.
With the arrival of spring, nature comes
alive. The summer months are pretty hot. The scorching heat, sweltering days,
and suffocating nights make living unbearable. The wet season is uninteresting.
Autumn is a wet season. The end of the fall season is not pleasant. The winter
season is bitterly cold and bleak. Spring has none of the drawbacks of the
other seasons. Every natural item regains its original state. Trees produce new
leaves regularly. Thousands of flowers blossom. They give a magnificent display
of colour and scent. Bees and butterflies are drawn to them because of the
range of hues. In pursuit of honey, they flutter from blossom to bloom.
Why does Bangladesh have six
seasons?
Summer is the first month of the Bengali
calendar. From the middle of April through June, the weather is hot and dry,
with an odd strong storm. The monsoon season lasts from mid-June to mid-August,
and it provides up to 85 percent of the year's total rainfall. Autumn is marked
by a steady reduction in temperature and humidity from mid-August to
mid-October, with temperatures dropping even further from mid-October to
mid-December in late autumn.
Winter, which lasts from mid-December to
mid-February, is Bangladesh's oldest and arguably most pleasant season, with
average temperatures of 11–20°C (52–68°F). Finally, from mid-February to
mid-April, spring arrives, with nice winds and occasional thunderstorms
punctuating the afternoons.
The seasonal change from six to
four seasons
The Bangla calendar's popularity and use in
Bangladesh are partly due to its adaption to the region's distinctive seasonal
variations. Bangladesh has a climate separated into six seasons, including the
rainy season and the dry season, as well as spring, summer, fall, and winter. A
high percentage of respondents in our poll believe that the timing of seasonal
shifts has become unpredictable. Locals and specialists also believe that the
six-season country is losing its seasonal variance and is transforming into a
four-season or minor nation, even though no prior studies have proved this.
We're using this calendar to see if
people's impressions of seasonal changes match actual climate data from the
Bangladesh Meteorological Department. More precisely, we analyzed four
significant climatic variables using climate data from the Dhaka meteorological
station: average daily maximum temperature, average daily lowest temperature,
average daily mean temperature, and average daily rainfall. We looked at all
possible pairs of two consecutive seasons in the Bangla calendar to see whether
they were merging into one.
First, we used fundamental graphical
analysis to look at the temporal trend of climatic variables in each season
from 1953 to 2010. Then, by splitting the sample of a climatic variable in each
season into two subsamples, we used non-parametric Mann-Whitney tests. Each
subsample represents an "old period" subsample from 1953 to 1984 or a
"recent period" subsample from 1985 to 2010. It's worth noting that
the expert's opinions in the survey were used to determine this division.
Mann-Whitney tests can be utilized to compare subsamples of a climatic variable
through time.
The purpose of this study is to see if the
Bangla yearly calendar changes from six to four seasons. To test this
hypothesis, we looked at all conceivable pairs of nearby seasons to see if a
climatic variable in the two seasons is becoming indistinguishable, or at the
very least getting less identifiable, over time. Temperature and rainfall in Dhaka,
where the most climatic data are available, are essential variables in
analyzing seasonal fluctuations. The two pairings of successive seasons that
support our "merging" theory are shown in the following subsection.
Because the other pairs' analyses denied the "merging" hypothesis, we
won't show the "rejected" findings.
Rainy season vs pre-autumn season
The rainy and pre-autumn seasons are two
Bengali seasons traditionally considered separate and thought to have important
but diverse influences on agriculture and daily life. Individual experiences
and weather data backed up this view. However, we believe that these seasons
have become increasingly identical or indistinguishable in recent years.
Summer season vs rainy season
Summer and rainy seasons are two Bengali
seasons traditionally regarded as separate. Based on the observations of
experts and locals, these two seasons are said to be merging. We examine each
climatic variable for the two seasons using the same technique previously. The
two trend lines for the rainy and summer seasons, on the other hand, maybe
considered to be getting closer over time.
Conclusion
The fundamental daily climatic variables of
temperature and rainfall were used to see if the yearly Bangladeshi calendar
shifts to four from six seasons. Surprisingly, two pairs of two successive
seasons in the Bangla calendar are merging or, at the very least, becoming
indistinguishable in recent periods. This evidence for seasonal shift must be
taken seriously since it significantly impacts Bangladeshi agriculture and
daily life, where present economic production systems have been adapted to six
season assumptions.
We believe that no previous articles have
identified evidence for seasonal change in a single nation. This Bangladeshi
evidence will serve as a starting point for further research into whether or
not additional probable seasonal changes exist in other regions of the world.
