Cloud Formations in Guanambi, Brazil

Guanambi, Brazil, experiences various cloud formations throughout the year. During the wet season (November to April), cumulonimbus clouds are common, bringing heavy rainfall and occasional thunderstorms. These clouds can rise several kilometers into the atmosphere, forming impressive anvil-shaped tops. Altostratus clouds are also prevalent during this time, covering the sky with a uniform gray layer that often produces drizzle.

In the dry season (May to October), cirrus clouds are frequently observed. These thin, wispy clouds are composed of ice crystals and appear high in the atmosphere. Stratus clouds may also occur, forming a low, uniform layer that can persist for several days, resulting in overcast conditions. Additionally, lenticular clouds, shaped like lenses, may appear in the Serra do Rio Grande mountain range due to the influence of airflow over the mountains.

Annual Precipitation Patterns

Guanambi, Brazil, experiences tropical savanna climate characterized by distinct wet and dry seasons. Annual precipitation levels average around 770 mm (30 in) but fluctuate significantly from year to year. The wet season typically spans from October to April, when heavy convective rainfall dominates. During this period, Guanambi receives an average of 600 mm (24 in) of rain, accounting for approximately 80% of the annual total.

Seasonal Variation

The dry season in Guanambi extends from May to September. During these months, precipitation is scarce, with average monthly totals below 50 mm (2 in). The lack of rainfall during this period is primarily due to the dominant influence of the trade winds, which promote dry and stable atmospheric conditions. However, even during the dry season, occasional thunderstorms can occur, providing temporary relief from the intense drought conditions.

Rainfall Patterns in Guanambi

Guanambi, a city located in northeastern Brazil, experiences a semi-arid climate with distinct wet and dry seasons. During the wet season, which typically lasts from November to April, Guanambi receives the majority of its annual rainfall, averaging around 800mm (31.5 inches). This rainfall is primarily associated with the Intertropical Convergence Zone (ITCZ), a meteorological feature that brings heavy rainfall to equatorial regions.

Rainfall Variability

Rainfall in Guanambi is highly variable, with some years experiencing significant fluctuations from the average. The city has faced severe droughts in the past, such as the one that occurred in 2012-2013. During this period, Guanambi received less than half of its average annual rainfall, leading to water shortages and agricultural losses. Conversely, occasional flooding events can also occur during the wet season, especially when heavy rainfall coincides with a high-pressure system that prevents moisture from escaping.

Historical Snowfall in Guanambi

On August 29, 2021, the city of Guanambi in the state of Bahia, Brazil, witnessed an unprecedented snowfall. This phenomenon, which is extremely rare in this part of the world, occurred during a cold front that brought sub-zero temperatures to the region. The snowfall lasted for approximately two hours, covering the city in a thin layer of white. While the snowfall was not significant enough to cause any major disruptions or damage, it was an awe-inspiring sight for the residents of Guanambi.

Possible Causes and Significance

The snowfall in Guanambi is believed to have been caused by a combination of factors, including the cold front, high altitude, and moisture. Guanambi is located at an altitude of approximately 900 meters (3,000 feet), which contributed to the cold temperatures necessary for snowfall. Additionally, the moisture from the Atlantic Ocean was carried inland by the cold front, providing the raw material for the snow formation. This event highlights the potential for extreme weather events in regions that are not typically associated with snow or cold temperatures. It also underscores the importance of understanding the interplay between atmospheric conditions and local topography in predicting and mitigating the impacts of weather-related phenomena.

Sunlight Hours

Guanambi, Brazil enjoys an abundance of sunshine throughout the year, with an average of 8-9 hours of sunlight per day. The sun’s intensity varies slightly depending on the time of year, with the highest levels occurring during the summer months (December to February) and the lowest levels during the winter months (June to August). However, even during the winter, Guanambi typically experiences at least 6 hours of sunlight per day.

Sun’s Position

The position of the sun in the sky changes throughout the day and year. At sunrise, the sun is located in the eastern horizon, and it gradually moves westward throughout the day. At noon, the sun reaches its highest point in the sky, known as the zenith. After noon, the sun continues to move westward, setting in the western horizon at sunset. The sun’s position also varies with the seasons. During the summer months, the sun is higher in the sky, providing more direct sunlight. Conversely, during the winter months, the sun is lower in the sky, resulting in less direct sunlight.

Moon’s Position and Visibility in Guanambi

The Moon’s position in the sky as seen from Guanambi, Brazil, varies throughout the month due to its orbit around Earth. The Moon’s rise and set times, as well as its elevation and phase, can be predicted using astronomical calculations. The Moon typically rises in the east and sets in the west, but the exact direction depends on the time of year and the Moon’s phase. During the full Moon, the Moon is visible all night long, while during the new Moon, it is not visible at all.

Influence on Tides and Illumination

The Moon’s gravitational pull has a significant influence on the tides in the ocean. In Guanambi, which is located inland, the tidal effects are less noticeable compared to coastal areas. However, the Moon’s gravity still causes slight variations in the water levels of rivers and lakes. Additionally, the Moon’s reflection of sunlight provides natural illumination at night. During the full Moon, the moonlight is bright enough to cast shadows and create a sense of ambient lighting.

Historical Humidity Data

Over the past few decades, Guanambi, Brazil has experienced significant variations in humidity levels. During the 1990s, the city experienced relatively high humidity, with average annual relative humidity values exceeding 70%. However, since the early 2000s, humidity levels have shown a gradual decline, dropping to an average annual relative humidity of around 60% in recent years. The lowest humidity levels are typically observed during the dry season, which runs from May to September.

Factors Influencing Humidity

Several factors contribute to the humidity levels in Guanambi. The city’s location in the semi-arid region of Brazil means that it receives low rainfall, which limits the amount of moisture available in the atmosphere. Additionally, the prevailing trade winds from the southeast carry dry air into the region, further reducing humidity levels. However, during the rainy season, from October to April, humidity levels increase as the influx of moisture-laden air from the Amazon basin increases. The city’s altitude, located at an elevation of around 900 meters above sea level, also influences humidity levels, as higher altitudes tend to have lower humidity than lower elevations.

Wind Patterns in Guanambi

Guanambi, Brazil, experiences a predominantly easterly trade wind pattern throughout the year. These winds originate over the Atlantic Ocean and carry moisture towards the continent. During the wet season (November to April), the trade winds are stronger and bring frequent rainfall to the region. Conversely, during the dry season (May to October), the trade winds weaken and Guanambi receives less precipitation. The average wind speed in Guanambi ranges from 10 to 15 kilometers per hour (6 to 9 miles per hour), with higher speeds occurring during the wet season.

Local Wind Variations

In addition to the trade wind pattern, Guanambi also experiences local wind variations. During the afternoon, a southerly sea breeze can develop, bringing cooler air from the coast. This sea breeze typically lasts until the late evening. Additionally, during the dry season, a northwesterly wind can occasionally occur, bringing warm and dry air from the interior of Brazil. This wind can sometimes cause discomfort and can contribute to the region’s aridity. Overall, Guanambi’s wind patterns are influenced by both regional and local factors, resulting in a diverse and dynamic wind regime throughout the year.
