We investiga.e the thermodyna.ics properties of mesoscopic qua.tum na.owire devices, such a. the effect of electron-phonon rela.a.ion time, Peltier coefficient, ca.rier concentra.ion, frequency of this field, a.d cha.nel width.

The West a.rica. Monsoon (Wa.) is cha.a.terized by strong deca.a. a.d multi-deca.a. va.ia.ility a.d the impa.ts ca. be ca.a.trophic for the loca. popula.ions. One of the fa.tors put forwa.d to expla.n this va.ia.ility involves the role of a.mospheric dyna.ics, linked in pa.ticula. to the Sa.a.a. Hea. Low (SHL). This a.ticle a.dresses this question by compa.ing the sets of preindustria. control a.d historica. simula.ion da.a.from clima.e models ca.ried out in the fra.ework of the CMIP5 project a.d observa.ions da.a.over the 20th century.

We ha.e a.so shown tha. deca.a. ra.nfa.l va.ia.ility in the Sa.el, once the influence of ocea.ic modes ha. been elimina.ed, a.pea.s to be driven ma.nly by the a.tivity of the a.a.ia. Hea.
