  abstract = {{S}nowpack significantly contributes to water resources in {N}orth {A}frica. {T}he objective of this work was to analyze the impact of the {N}orth {A}tlantic {O}scillation ({NAO}) on rainfall and temperature in {M}orocco at a sub-seasonal scale and to evaluate, for the first time, linkages between the {NAO} and snow cover area ({SCA}) derived from remote sensing observations. {F}or this purpose, we analyzed daily {SCA} products (2000-2013) from the {MODIS} sensor, meteorological data from 37 stations (1993-2011), {NCEP} re-analysis of surface air temperature and rainfall rate, and a monthly {NAO} index. {T}he linear linkages sought using simple correlation analysis demonstrated that negative (positive) {NAO} (1) is associated with enhanced (reduced) rainfall in {D}ecember and {F}ebruary for the northern part of the country; (2) occurs with above-normal (below-normal) temperature and, in contrast with rainfall, the correlation persists far inland and late in the season. {T}hese results highlight a possible competing influence of {NAO} on the snowpack dynamic through rainfall and temperature. {I}ndeed, negative (positive) {NAO} tends to favor earlier (later) melting and lesser (greater) {SCA} in spring ({A}pril-{M}ay) through milder temperatures. {R}esults have direct implications for seasonal forecast of {SCA} in {M}orocco.},
