D-2: contrasted weather conditions in Peru

Weather forecast in Peru today:

19°C in Lima, dry climate (Costal area)
25°C during the day and 16°C during the night in Nazca (Coastal area)

24°C during the day and 0°C during the night in Huaraz and Cusco (Andes)
24°C in Iquitos @ 94% humidity with thunderstrorms (Amazone)
32°C in Tarapoto @99% humidity with thunderstrorms (Amazone)

I think with this more or less in line with this precipitation map:

precipitation Peru (AGteca)

These very diverse climates come from the geography of Peru which is divided into three contrasting topographical regions:

1. The coast (costa)
2. The highlands (sierra)
3. The eastern rainforests (selva)

Altitude and cities of Peru

Each of these climatic zones are very specific in terms of topography, land, climate, agriculture, ethnic groups and remain culturally very strong. Therefore, this gives room to plenty different forms of food and cooking throughout the country.

1. Costa

“The coastline is a narrow ribbon of desert plain from 16 to 160 km broad. It is scored by 50 rivers, which water some 40 oases. Only a few of these rivers, which have their source in the Andean snowbanks, reach the sea in all seasons. Although the coastal region constitutes only 12% of the national territory, it contains the ports and chief cities of Peru.”

2. Sierra

“Inland, the low costa rises through the steep wastes of the high costa (760–2,000 m/2,500–6,500 ft), then ascends abruptly to the western cordillera (Cordillera Occidental) [which] runs parallel to the coast. […The Andes] branch off to the southeast, [to] Lake Titicaca, the highest large navigable lake in the world (about 3,810 m/12,500 ft high), which is bisected by the Peruvian-Bolivian border. Of the 10 Peruvian peaks that rise above 5,800 m (19,000 ft), Huascarán, 6,768 m (22,205 ft), is the highest. […] The Andes form the sierra and constitute 27% of the country’s surface.”

3. Selva

“The most important rivers draining the Andes on the Atlantic watershed, such as the Marañón, Huallaga, and Ucayali, flow north or south and eventually east to form the Amazon Basin. The selva covers 61% of Peru and consists of the low selva (the Amazon rainforest) and the high selva, a steeply sloping transition zone about 100–160 km (60–100 mi) wide between the sierra and the rain forest.”
