Snow in Brazil

Snow in Brazil is a earth science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Snow in Brazil rather than just read about it. In short: Snow in Brazil occurs yearly in the high plains of the country's South Region (comprising the states of Rio Grande do Sul, Santa Catarina, and Paraná). Elsewhere in the country it is a rare phenomenon but has been registered several times.

Key takeaways

Snow in Brazil belongs to earth science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Snow in Brazil to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Snow in Brazil from memory before moving on to harder problems.

Reference excerpt

Snow in Brazil occurs yearly in the high plains of the country's South Region (comprising the states of Rio Grande do Sul, Santa Catarina, and Paraná). Elsewhere in the country it is a rare phenomenon but has been registered several times. The phenomenon occurs mainly during the months of June, July and August. In this period, São Joaquim, the city with the most snow days, receives an average of 13,000 visitors from other parts of Brazil. The greatest snowfall ever recorded in the country occurred in Vacaria (RS) on 7 August 1879, with more than 2 metres (79 inches) of accumulated snow. Snowfalls like this are extremely rare in Brazil, the two below being the only later snowfalls that reached (or passed) 1 metre (39 inches):

20 July 1957, in São Joaquim, Santa Catarina, with 1.3 metres (51 inches) of snow. Often cited as the greatest snowfall in Brazil. 15 June 1985, in Pico das Agulhas Negras, Itatiaia, Rio de Janeiro. 1 metre (39 inches) of snow.

By region

South Due to the high latitude and large areas of high altitude, the South Region is easily the coldest in Brazil, with snow tending to occur every year in southern municipalities like São Joaquim (SC), Urubici (SC), Urupema (SC), and São José dos Ausentes (RS), as well as Bom Jesus (RS), Bom Jardim da Serra (SC), Cambará do Sul (RS), and Palmas (PR). Those are considered the coldest cities in the country.

Although the snow is normally restricted to higher elevation, there are also many reports of snow at low elevation such as Ijuí and Porto Alegre (330 metres (1,080 feet) and 10 metres (33 feet) above sea level, respectively).

In 2000, snow occurred in more than 70 municipalities spread throughout the three states of the Southern Region. In 2010, snow was recorded in 21 municipalities of the Santa Catarina and Rio Grande mountains. In the year 2013, a historic episode in July brought snow to more than 140 cities in the region, including the country's coldest capital Curitiba (PR), which experienced snowfall once more after the last occurrence 38 years before and is home of 1.8 million inhabitants.

Other regions Snow has been registered in the southeastern states of São Paulo (last time in Apiaí in 1975), Rio de Janeiro (last time at Itatiaia, at the Pico das Agulhas Negras, in 1985), and Minas Gerais. It has also been registered twice (1975 and 2013) in Paranhos, Mato Grosso do Sul, located in the Center-West. This totals seven states with snow reported in the country. The remaining states, including the whole regions of North and Northeast, have strong tropical and semi-arid climates and low latitude and altitude, making snow (virtually) impossible. There have been no reports of snow even at the highest point in the country, Pico da Neblina.

Worked examples

Example 1 — a first encounter with Snow in Brazil

Start with the simplest possible case. Write down what Snow in Brazil claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Snow in Brazil before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Snow in Brazil ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Snow in Brazil

In research: Snow in Brazil appears in earth science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Snow in Brazil in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Snow in Brazil is common in secondary-school and first-year university syllabi. It links to neighbouring topics Climate of Brazil, Snow by country, Water in Brazil, so understanding it makes those chapters shorter.
In everyday life: Look for Snow in Brazil outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
