If you set Row_num or Column_num to 0 (zero), INDEX returns the array of values for the entire column or row, respectively. To use values returned as an array, enter the INDEX function as an array formula in a horizontal range of cells for a row, and in a vertical range of cells for a column.
Climate The climate of the western part of the cordillera is moist and mild but is influenced by the closeness of a large body of water. This is also known as maritime climate meaning the winters are usually above freezing and summers are cooler than in the interior of the continent.
The high peaks of the Cordillera Occidental to the west have a cool climate, and cold winds blow in the Altiplano (the high plains separating Bolivia's two mountain ranges). In the northern Altiplano, however, the climate is moderated by Lake Titicaca.
