The PAMPAS (from Quechua pampa, meaning "plain") are fertile South
American lowlands, covering more than 750,000 km2 (289,577 sq mi),
that include the Argentine provinces of
The climate is warm, with precipitation of 600 to 1,200 mm (23.6 to 47.2 in), more or less evenly distributed through the year, making the soils appropriate for agriculture . This area is also one of the distinct physiography provinces of the larger Paraná -Paraguay Plain division.

Winters are generally mild, although cold waves do occur. Normal
temperatures range from 12 to 19 °C (54 to 66 °F) during the day,
and from 1 to 6 °C (34 to 43 °F) at night. With strong northerly
winds, days of over 25 °C (77 °F) can be recorded almost everywhere,
whereas during cold waves, high temperatures can be only 6 °C (43
°F). Frost occurs everywhere in the Pampas, although it is much more
frequent in the southwest, and less so around the Parana and Uruguay
Rivers. Temperatures under −5 °C (23 °F) can occur everywhere,
whereas values of −10 °C (14 °F) or lower are confined to the
south and west.
Springs are very variable; it is warmer than fall in most areas (especially in the west), but significantly colder along the Atlantic. Violent storms are more common, as well as wide temperature variations: days of 35 °C (95 °F) can give way to nights of under 5 °C (41 °F) or even frost, all within only a few days.
Precipitation ranges from 1,200 mm (47 in) in the northeast, to about 500 mm (20 in) in the southern and western edges. In the west, it is highly seasonal, with some places recording averages of 120 mm (4.7 in) monthly in the summer, and only 20 millimetres (0.8 in) monthly in the winter. The eastern areas have small peaks in the fall and in the spring, with relatively rainy summers and winters that are only slightly drier. However, where summer rain falls as short, heavy storms, winter rain falls mostly as cold drizzle, so that the amount of rainy days is fairly constant. Very intense thunderstorms are common in the spring and summer, and it has among the most frequent lightning and highest convective cloud tops in the world. The severe thunderstorms produce intense hailstorms , and both floods and flash floods , as well as the most consistently active tornado region outside the central and southeastern US.
Herbivores of the pampas are the pampas deer , guanaco , gray brocket , dwarf mara , plains viscacha , Brazilian guinea pig , southern mountain cavy and coypu . The biggest predator of the region is the puma followed by the maned wolf , pampas fox , geoffreys cat , lesser grison as well as the omnivorous white-eared opossum and molinas hog-nosed skunk .
Bird species of the pampas are ruddy-headed goose , pampas meadowlark , hudsonian godwit , maguari stork , white-faced ibis , white-winged coot , southern screamer , dot-winged crake , curve-billed reedhaunter , burrowing owl and the rhea .

Frequent wildfires ensure that only small plants such as grasses
flourish, while trees are less common. The dominant vegetation types
are grassy prairie and grass steppe in which numerous species of the
Stipa are particularly conspicuous. "

Winters are cool to mild and summers are very warm and humid. Rainfall is fairly uniform throughout the year, but is a little heavier during the summer. Annual rainfall is heaviest near the coast and decreases gradually further inland. Rain during the late spring and summer usually arrives in the form of brief heavy showers and thunderstorms. More general rainfall occurs the remainder of the year as cold fronts and storm systems move through. Although cold spells during the winter often send nighttime temperatures below freezing, snow is quite rare. In most winters, a few light snowfalls occur over inland areas.
