  abstract = {{T}his paper focuses on the representation of the air surface temperature and precipitation using high spatiotemporal simulations (3 km-1 h) of the {WRF}3.7.1 model in the central {P}eruvian area. {I}t covers, from east to west, the coastal zone, the western slope of the {A}ndes, the {A}ndean {M}antaro basin (500-5000 masl), and the {A}ndes-{A}mazon transition region in the eastern {A}ndes. {T}he study covers the {J}anuary months from 2004 to 2008. {T}hree experiments were conducted using different topography and land use data sources: (1) a control simulation using the default {WRF} topography and land use datasets from the {U}nited {S}tates {G}eological {S}urvey ({USGS}); (2) a simulation changing only the topography by using the {SRTM} topography dataset; and (3) a simulation changing the land use data of (2) by a new dataset adapted from {E}va et al. (2004). {SRTM} topography performed better than the control simulation for representing the actual altitudes of 57 meteorological stations that were used for precipitation and surface air temperature data. {A}s a result, the simulations of experiments (2) and (3) produced lower bias values than that of (1). {T}opography change (experiment (2)) showed improvements in temperature bias that were directly associated with linear modifications of -5.6 and -6.7 degrees {C}.km(-1) in minimum and maximum temperature, respectively. {I}ncreasing (decreasing) precipitation with topography or land use change was clearly controlled by changes in the moisture flux patterns and its convergence (divergence) in the {A}ndes-{A}mazon transition. {O}n the western slope, precipitation increase could be associated with the increase in easterly flow by the smaller altitudes of the {A}ndes mountains in {SRTM} topography and by increasing evaporation with new land use. {I}nside the {M}antaro {B}asin, low level moisture flux seems to control the rainfall changes. {O}verall, relative changes (positive or negative) in precipitation due to topography or land use change could reach values above 25%.},
