During this time, precipitation levels decline significantly, with monthly averages typically below 50 millimeters (2 inches). June and July are the driest months, with average rainfall of around 25 millimeters (1 inch). This seasonal variation in precipitation is primarily driven by the seasonal shift in the ITCZ, which influences the amount of moisture available in the atmosphere for condensation and rainfall.

Long-Term Precipitation Trends

Long-term precipitation data for Sumare, Brazil, indicate a general upward trend over the past several decades. This trend is consistent with observed increases in global precipitation patterns attributed to climate change. Studies suggest that rising global temperatures have intensified the hydrological cycle, leading to increased evaporation and subsequent precipitation. In Sumare, this trend has manifested as a gradual increase in annual precipitation, with the wet season becoming marginally wetter and the dry season slightly less dry. However, it is important to note that year-to-year variations in precipitation can occur due to natural climate variability and other factors, such as El Nino-Southern Oscillation (ENSO) events.

Historical Occurrence

Snowfall in Sumare, Brazil, is a rare meteorological phenomenon that has occurred only a handful of times in recorded history. The most recent occurrence was on July 19, 1918, when the city experienced a light dusting of snow. Prior to that, snowfall had been documented in Sumare on July 27, 1890, and August 2, 1901. These events generated widespread astonishment and disbelief, as snowfall is extremely unusual in the tropical climate of southeastern Brazil.

Meteorological Conditions

The formation of snow in Sumare requires a specific combination of meteorological conditions. First, the temperature at ground level must drop below 0°C (32°F). This can occur when cold air originating from the South Pole travels northward and encounters the relatively warmer air masses over Brazil. Second, there must be sufficient moisture in the atmosphere to allow for condensation and freezing. This can occur through the convergence of air currents or the presence of a cold front. Finally, the air must be relatively calm to allow for snow crystals to form and accumulate on the ground.

Sunrise and Sun Times in Sumare, Brazil

In Sumare, Brazil, the time of sunrise and sunset varies throughout the year due to the Earth’s tilt and location relative to the sun. During summer (December to February), the sun rises around 5:30 AM local time and sets around 7:30 PM. The longest day of the year occurs around December 21st, with approximately 13 hours and 10 minutes of daylight.

In winter (June to August), sunrise occurs around 7:00 AM and sunset around 5:30 PM. The shortest day of the year is around June 21st, with approximately 10 hours and 50 minutes of daylight. These times can vary slightly depending on factors such as atmospheric conditions and cloud cover.

Moon’s Influence on Sumare

The gravitational pull of the moon has a significant impact on the tides of Lake Jacarey in Sumare, Brazil. During full and new moons, the gravitational forces combine with the centrifugal force of the Earth’s rotation, creating higher high tides and lower low tides, known as spring tides. Conversely, during quarter moons, the opposing gravitational forces diminish the tidal range, resulting in smaller, neap tides. The moon’s gravitational pull also affects the flow of water in rivers and streams surrounding Sumare, particularly during spring tides when the increased tidal currents can alter the flow patterns.

Lunar Calendar in Sumare

The phases of the moon have long been used for timekeeping and agricultural practices in Sumare. The indigenous Guarani people, who have inhabited the region for centuries, have traditionally relied on the lunar calendar to determine the best time for planting and harvesting crops.
