Khí hậu nhiệt đới – Bản sắc và Tiềm năng của Việt Nam

Located entirely within the Northern Hemisphere, with diverse and differentiated terrain, Vietnam is favored by a typical tropical climate. These unique characteristics have created the identity and outstanding development potential of our country. In this article, we will learn more about the tropical climate in Vietnam, from its characteristics to its practical applications.

Our country is located entirely within the Northern Hemisphere’s tropical zone, so it has a tropical climate.

Unique geographical location of Vietnam

Vietnam lies entirely within the Northern Hemisphere’s tropical zone, with a geographical range from 8°27′ to 23°23′ North latitude and from 102°08′ to 109°30′ East longitude. This location puts Vietnam within the area of ​​influence of monsoon systems and tropical air masses.

Dominance of monsoon systems

Monsoons are one of the main factors that characterize the tropical climate in Vietnam. Throughout the year, Vietnam is influenced by two main monsoon systems: the Northeast Monsoon and the Southwest Monsoon.

Northeast’s wind

In winter, Vietnam is affected by the Northeast Monsoon. Cold air masses from Northwest China and Mongolia move south, bringing cold, dry winds and little rain. The Northeast Monsoon usually lasts from November to April of the following year.

Southwest Monsoon

In summer, Vietnam is affected by the Southwest Monsoon. Hot and humid air masses from the Indian Ocean move north, bringing persistent rains and high temperatures. The Southwest Monsoon usually lasts from May to October.

The impact of tropical air masses

In addition to the influence of monsoon systems, Vietnam’s climate is also strongly influenced by tropical air masses. Throughout the year, Vietnam is located within the influence of tropical air masses, such as the Indian Ocean, Pacific Ocean and Northern Ocean.

The interaction between monsoon systems and tropical air masses has created a typical tropical climate for Vietnam, with hot and humid summers and cool winters.

Characteristics of tropical climate in our country

The tropical climate in Vietnam exhibits distinct characteristics, including high temperatures, abundant rainfall, high humidity and abundant light.

High temperature

The average annual temperature in Vietnam ranges from 22-27°C. The highest temperatures usually occur in June-August, with temperatures reaching up to 40°C, especially in the Central and Central Highlands regions. In winter, temperatures usually range from 15-20°C, and can even drop below 10°C in mountainous areas such as Sapa.

Abundant rainfall

The average annual rainfall in Vietnam ranges from 1,500 to 2,500 mm. The rainy season usually lasts from May to October, with rainfall accounting for 75 to 85% of the total annual rainfall. The Central and Central Highlands regions often have higher rainfall than other regions.

High humidity

The average annual humidity in Vietnam usually fluctuates between 80-90%. The highest humidity usually occurs during the rainy season, when the southwest monsoon systems carry a lot of moisture from the Indian Ocean.

Abundant light mode

Vietnam is located in the tropics, so the light regime throughout the year is abundant. The average number of hours of sunlight per year ranges from 1,500-2,500 hours, depending on the region.

The above characteristics of temperature, rainfall, humidity and light have created the unique identity of the tropical climate in Vietnam, deeply affecting the natural environment, ecology and people’s lives.

The influence of monsoon on tropical climate in our country

The change in direction and speed of monsoon winds throughout the year is one of the main factors that create the differentiation of tropical climate in Vietnam.

Northeast Monsoon Season

In winter, when the Northeast monsoon blows, the climate in Vietnam becomes cold and dry, with temperatures often lower than in summer. Rainfall also decreases significantly, mainly concentrated in the Northern and North Central regions.

Southwest Monsoon Season

When the southwest monsoon blows in the summer, the climate in Vietnam becomes hot and humid, with high temperatures and abundant rainfall. Rains often occur, especially in the Central and Central Highlands regions.

Monsoon changes and their effects on climate

The change in direction and speed of monsoon winds throughout the year alters key climatic factors such as temperature, rainfall, humidity and light. This creates tropical climate differentiation in different regions of Vietnam.

Differentiation of tropical climate in regions of our country

Due to the influence of diverse terrain, changes in monsoons and air masses, the tropical climate in Vietnam shows clear differentiation between regions.

The Northern region

Northern Vietnam is strongly influenced by the Northeast monsoon in winter, bringing cold air and little rain. In summer, the Southwest monsoon brings high temperatures and abundant rain. The complex terrain with high mountain ranges also contributes to the difference in climate between regions.

Central region

Central Vietnam is located in an area directly affected by the southwest monsoon in the summer, with high temperatures and abundant rainfall. However, due to the rugged terrain with the Truong Son mountain range running along it, the climate in the Central region has a clear differentiation between the coastal and mountainous areas.

Highlands region

The Central Highlands is considered a “typical tropical climate zone” of Vietnam. This region is strongly influenced by the southwest monsoon, with high temperatures and abundant rainfall. The rugged terrain with high mountain ranges also creates differences in climate between sub-regions.

Southern region

Southern Vietnam has a tropical climate almost all year round, due to its location within the influence of the southwest monsoon. Temperatures are consistently high, rainfall is abundant, with the rainy season lasting from May to November. The relatively flat terrain also contributes to the uniformity of the climate in the region.

The differentiation of tropical climates between regions is a characteristic of Vietnam, resulting from the interaction between topographic factors, monsoons and air masses.

The impact of terrain on tropical climate in our country

Vietnam’s diverse and complex terrain is one of the important factors creating tropical climate differentiation throughout the country.

The influence of the Truong Son mountain range

The Truong Son mountain range running along central Vietnam is an important geographical barrier, separating the climate between the coastal and mountainous areas. On the western slopes, the climate becomes colder and wetter, while on the eastern slopes, the climate is warmer and drier.

The role of the Central Highlands

The Central Highlands with an average altitude of 500-800 m above sea level creates a special climate. The temperature here is usually lower than in the plains, with abundant rainfall and high humidity.

The influence of river systems

Vietnam’s dense river system also contributes to the differences in climate. River valleys are often wetter than neighboring regions.

Distribution of highland regions

High mountain ranges such as Hoang Lien Son in the North, Truong Son range in the Central region and Lam Vien plateau in the Central Highlands create differences in temperature, rainfall and humidity between the mountains and the plains.

The impact of terrain on tropical climate in Vietnam is one of the important factors creating diversity and differentiation of climate in the whole country.

Advantages and challenges of tropical climate for Vietnam

Tropical climate has its own advantages and challenges for Vietnam, a country located entirely within the Northern Hemisphere’s tropical zone.

Advantage

With a tropical climate, Vietnam has favorable conditions for the development of agriculture, aquaculture and livestock. Stable temperatures all year round and suitable rainfall help crops grow strongly and diversely. At the same time, the warm climate is also favorable for tourism, helping to develop our country’s tourism industry.

Challenge

However, with a tropical climate, Vietnam also faces many challenges. Climate change is increasingly serious, increasing the risk of natural disasters, droughts and floods. Rising temperatures also affect human health and the lives of living things.
