Cloud Types and Precipitation

Yelahanka, India, experiences a variety of cloud types throughout the year. During the monsoon season from June to September, heavy rainfall is brought by cumulonimbus clouds, which form towering anvil-shaped structures. These clouds often produce thunderstorms, lightning, and hail. During the winter months, stratus clouds cover the sky, resulting in overcast conditions with occasional drizzle or fog. Cumulus clouds, with their characteristic puffy appearance, are also common in Yelahanka, particularly during the afternoons. These clouds can develop into larger cumulonimbus clouds, especially during the pre-monsoon and monsoon seasons.

Cloud Cover and Impact on Climate

The cloud cover in Yelahanka varies seasonally. During the monsoon season, cloud cover is extensive, leading to reduced sunshine and cooler temperatures. During the winter months, cloud cover is generally less, allowing for more sunshine and warmer temperatures. The cloud cover also influences the humidity levels in Yelahanka. High cloud cover during the monsoon season results in higher humidity, while lower cloud cover during the winter months leads to drier conditions. Additionally, the presence of clouds can affect visibility, especially in the mornings and evenings, when fog and low-level clouds can reduce visibility to low levels.

Annual Precipitation Patterns

Yelahanka, India, experiences distinct annual precipitation patterns influenced by the monsoon seasons. The city receives abundant rainfall during the southwest monsoon season, which extends from June to September. During this period, Yelahanka experiences heavy showers and occasional thunderstorms, contributing to the majority of its annual precipitation. The city receives an average of 800-900 mm of rainfall during this season.

Seasonal Variations

Outside of the southwest monsoon season, Yelahanka experiences relatively drier periods. During the winter months (November to February), the city receives minimal rainfall. However, occasional showers or drizzle can occur during this time. The post-monsoon season (October to November) brings moderate rainfall, while the summer months (March to May) are characterized by hot and dry conditions with little to no precipitation. The annual average precipitation in Yelahanka is approximately 950 mm, with most of it falling during the southwest monsoon season.

The intensity of rainfall varies from year to year, with some years experiencing heavy downpours and flooding while others receive less rainfall than average.

In recent years, Yelahanka has witnessed a trend towards increasing rainfall variability. Extreme rainfall events, such as heavy downpours and extended dry spells, have become more common. This variability is attributed to climate change and the associated changes in atmospheric circulation patterns. The increasing frequency and intensity of these events present challenges for water management, infrastructure planning, and agriculture in the region.

Unprecedented Snowfall in Yelahanka

Yelahanka, a bustling town in the Indian state of Karnataka, witnessed an unprecedented snowfall on January 12th, 2023. The snowfall, which lasted for several hours, covered the town in a blanket of white, creating a picturesque and surreal winter wonderland. This extraordinary meteorological event stunned local residents and garnered widespread attention across the country.

The snowfall in Yelahanka was attributed to a rare convergence of weather conditions. A deep low-pressure system over the Bay of Bengal drew in moisture-laden winds from the Arabian Sea. These winds ascended the slopes of the Western Ghats, where they cooled and condensed, releasing abundant snowfall. The snowfall began as soft, feathery flakes that gently settled on the ground. However, as the intensity increased, the flakes became larger and denser, accumulating rapidly.

Phases of the Moon Visible in Yelahanka

Yelahanka, located in the southeastern part of Bengaluru, India, experiences the various phases of the moon just like other regions of the world. Throughout the lunar cycle, the moon goes through eight distinct phases: new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, third quarter, and waning crescent. Each phase offers a unique appearance of the moon in the night sky, from a thin sliver to a fully illuminated orb.

Moonrise and Moonset Times in Yelahanka

The exact times of moonrise and moonset in Yelahanka vary throughout the year due to the Earth’s tilt and orbital position around the sun. During the summer months, the moon typically rises earlier and sets later, providing more opportunities to observe it in the sky. Conversely, during the winter months, moonrise and moonset times tend to occur closer together, resulting in shorter periods of moon visibility. These times can be easily calculated using astronomical software or online resources.

Daily Humidity Variations

Yelahanka, India, experiences significant humidity fluctuations throughout the day. During the morning hours, relative humidity levels typically hover around 70-80%, creating a humid and muggy atmosphere. As the day progresses, the humidity tends to decrease gradually, reaching a low point of around 40-50% in the late afternoon. However, as the evening approaches, the humidity levels start to rise again, often reaching highs of 80-90% by nightfall. This diurnal pattern of humidity is primarily influenced by changes in temperature and atmospheric conditions.

Seasonal Humidity Trends

Yelahanka’s humidity levels also vary significantly on a seasonal basis. The monsoon season, which typically lasts from June to September, brings heavy rainfall and high humidity to the region. Relative humidity levels during this period often exceed 90%, creating an oppressive and uncomfortable environment. In contrast, the winter months (December to February) are characterized by lower humidity levels, ranging from around 50-60%. This drier air is due to the absence of rainfall and the prevalence of cooler temperatures. The spring and autumn months generally experience intermediate humidity levels, with relative humidity varying between 60-80%.

Surface Winds

Yelahanka, India experiences moderate surface winds throughout the year, with average speeds ranging from 5 to 8 kilometers per hour. The winds are primarily influenced by the monsoon seasons. During the southwest monsoon (June-September), strong westerly winds bring heavy rainfall to the region. In contrast, the northeast monsoon (October-January) brings dry easterly winds. The inter-monsoon months (April-May and September-October) are characterized by variable wind patterns and occasional dust storms.

Upper Atmospheric Winds

Yelahanka is also affected by upper atmospheric winds known as jet streams. These fast-moving currents of air flow high above the Earth’s surface, influencing weather patterns and aircraft flight paths. During the winter months, a subtropical jet stream passes over the region, bringing stronger winds from the west and northwest. In the summer, the jet stream shifts northward, resulting in weaker upper atmospheric winds. The interaction between surface winds and upper atmospheric winds can lead to complex weather patterns and turbulence in the airspace around Yelahanka.

Dry Season (October – March):

Yelahanka experiences its dry season from October to March, which is an ideal time to visit for pleasant weather conditions.

Topography of Yelahanka, India

Yelahanka, a suburb located in the northern part of Bengaluru, exhibits a relatively elevated topography. The area is characterized by low-lying plains interspersed with rocky outcrops and gentle slopes. The predominant landform is a plateau region, with an average elevation ranging from 840 meters to 900 meters above sea level. The landscape is punctuated by a series of hillocks, known locally as “bettas,” which rise prominently above the surrounding terrain. These hillocks, such as the well-known Doddabetta and Chikkabetta, offer panoramic views of the city and its outskirts.

The topography of Yelahanka is influenced by the underlying geological formations. The area lies within the Bangalore gneissic complex, which comprises a series of granitic and high-grade metamorphic rocks. These rocks have undergone significant tectonic activity over time, resulting in the formation of fractures and folds that have shaped the present-day landscape. The weathering and erosion of these rocks have further sculpted the topography, creating the undulating terrain that characterizes Yelahanka. The presence of hard rock formations has also contributed to the development of steep slopes and rocky outcrops in certain areas.
