As Kerala India Weather December takes center stage, this comprehensive passage beckons readers into a world of diverse geography, intricate weather patterns, and fascinating insights. Kerala, a state in southern India, is known for its tropical monsoon climate, where the weather is influenced by its unique geography.
The state’s location on the Malabar Coast, surrounded by the Arabian Sea to the west and the Western Ghats mountain range to the east, creates a microclimate that is characterized by high temperatures, high humidity, and heavy rainfall during the monsoon season. Kerala’s weather in December falls within the post-monsoon period, and the state experiences a mild climate with average temperatures ranging from 20°C to 28°C (68°F to 82°F).
Understanding Typical Weather Patterns in Kerala, India During December
Kerala, a southern Indian state, is known for its geographical diversity, featuring coastal regions, backwaters, and mountainous hills. The state’s regional geography plays a significant role in shaping its weather patterns during December. Kerala’s coastal location enables the state to receive a significant amount of monsoon rainfall during the southwest monsoon season, which typically ends by mid-October. The state’s geography also creates a microclimate, where the temperature and humidity levels are influenced by the surrounding mountains and water bodies.
Regional Geography and Its Impact on Weather
Kerala’s unique geography, featuring the Western Ghats mountain range and the Arabian Sea coastline, creates a microclimate that affects the state’s weather. The Western Ghats act as a barrier to the southwest monsoon winds, resulting in high levels of rainfall in the eastern parts of the state. The Arabian Sea, being warmer than the Indian Ocean, contributes to the high humidity levels in the region. These geography-related factors influence the temperature and rainfall patterns in Kerala, particularly in December.
Interaction between Oceanic and Atmospheric Conditions
The interaction between the oceanic and atmospheric conditions plays a crucial role in shaping Kerala’s weather patterns. The warm waters of the Arabian Sea and the Indian Ocean heat the atmosphere above, leading to the formation of a warm and humid air mass. This air mass interacts with the cooler air from the Himalayas, resulting in the formation of the southwest monsoon winds. In December, these winds have started to retreat from the region, leaving behind a relatively dry and warm air mass. The temperature and humidity levels in the region are influenced by the interaction between these two air masses.
Typical Temperature Range for December
During December, Kerala experiences a relatively mild winter season, with the average temperature ranging from 22°C to 28°C (72°F to 82°F). The maximum temperature during the day rarely exceeds 30°C (86°F), while the minimum temperature at night ranges from 18°C to 22°C (64°F to 72°F). The temperature variation between day and night is relatively small, with an average difference of 4°C to 6°C (7°F to 11°F).
Previous Years’ Weather Patterns in Kerala, Kerala india weather december
In recent years, Kerala has experienced varying weather patterns in December. In 2019, the state experienced above-average rainfall, with the Western Ghats receiving heavy showers due to the prevailing westerly winds. In contrast, 2020 saw below-average rainfall, with the state experiencing a dry spell due to the prevailing easterly winds. In 2021, Kerala experienced a relatively normal weather pattern, with moderate rainfall and temperatures in December.
- In 2015, Kerala experienced heavy rainfall in December, resulting in flash floods and landslides in the Western Ghats region.
- In 2018, the state experienced a dry spell, leading to water scarcity and drought-like conditions in several districts.
Kerala’s weather patterns are influenced by the changing wind patterns, which in turn depend on the El Niño-Southern Oscillation (ENSO) and the Indian Ocean Dipole (IOD) phenomena.
Rainfall and Monsoon Patterns in Kerala During December
Rainfall in Kerala during December is an essential phenomenon that significantly impacts the state’s climate and agricultural activities. December marks the beginning of the northeast monsoon season in Kerala, which typically lasts until March. The southwest monsoon, which prevails during the summer months, also has an influence on the rainfall patterns in Kerala.
During December, the Indian Ocean, which borders Kerala’s west coast, plays a crucial role in shaping the state’s rainfall patterns. The Indian Ocean’s temperature and atmospheric pressure fluctuations contribute to the southwest monsoon’s variability, leading to changes in rainfall intensity and distribution. Furthermore, the Western Ghats, a mountain range that runs along Kerala’s western edge, forces the moisture-laden air to rise, resulting in orographic rainfall, which is a significant contributor to Kerala’s total rainfall.
Influence of the Indian Ocean on the Southwest Monsoon in Kerala
The Indian Ocean’s temperature, atmospheric pressure, and wind patterns have a profound impact on the southwest monsoon in Kerala. The ocean’s temperature fluctuations, particularly the warming and cooling of the Arabian Sea, can lead to variations in the southwest monsoon’s strength and duration. Additionally, changes in the atmospheric pressure over the Indian Ocean can also influence the monsoon’s trajectory and intensity, ultimately affecting rainfall patterns in Kerala.
The Indian Ocean’s influence on the southwest monsoon is evident in the following statistics:
- The Indian Ocean’s warming by 0.5°C can lead to a 10-15% increase in the southwest monsoon’s rainfall in Kerala.
- Changes in the atmospheric pressure over the Indian Ocean can result in variations of up to 20% in the southwest monsoon’s rainfall.
- The southwest monsoon’s rainfall in Kerala can increase by up to 15% with a 1°C warming of the Arabian Sea.
Role of the Western Ghats in Shaping Kerala’s Rainfall Patterns
The Western Ghats, a mountain range that runs along Kerala’s western edge, play a crucial role in shaping the state’s rainfall patterns. The Western Ghats force the moisture-laden air to rise, resulting in orographic rainfall, which contributes significantly to Kerala’s total rainfall. The Western Ghats also act as a barrier, redirecting the flow of moist air towards the eastern regions of Kerala, resulting in increased rainfall in those areas.
In Kerala, the Western Ghats’ influence on rainfall is evident in the following:
- The Western Ghats receive an average annual rainfall of over 7,000 mm, which is significantly higher than the state’s average rainfall.
- The Western Ghats receive 70-80% of Kerala’s total rainfall, mainly in the form of orographic rainfall.
- The Western Ghats’ mountainous terrain creates ideal conditions for orographic rainfall, resulting in heavy rainfall in the region during the southwest monsoon.
Different Types of Rainfall Experienced in Kerala and Their Distribution
Kerala experiences various types of rainfall during the course of the year, each with its unique characteristics and distribution. The southwest monsoon, which prevails during the summer months, brings heavy rainfall to the state. The northeast monsoon, which begins in December, is characterized by less intense rainfall compared to the southwest monsoon.
In Kerala, the following types of rainfall are experienced:
- Southwest monsoon: This type of rainfall is characterized by heavy rainfall and strong winds. The southwest monsoon brings significant rainfall to Kerala, particularly during the summer months.
- Northeast monsoon: This type of rainfall is characterized by less intense rainfall compared to the southwest monsoon. The northeast monsoon brings moderate rainfall to Kerala, particularly during the winter months.
- Orographic rainfall: This type of rainfall occurs when moist air rises over the Western Ghats, resulting in heavy rainfall in the region.
Comparison of Rainfall During December with the Average Monthly Rainfall in Kerala
December marks the beginning of the northeast monsoon season in Kerala. The rainfall during December is significantly lower compared to the average monthly rainfall in the state. However, the rainfall during December is crucial for agriculture and water supply in Kerala.
The following table compares the rainfall during December with the average monthly rainfall in Kerala:
| Rainfall (mm) | December | Average Monthly Rainfall |
|---|---|---|
| Southwest monsoon | 400-500 | 800-1,000 |
| Northeast monsoon | 200-300 | 100-200 |
