  A series of recent experiments on the Nernst effect, upper critical field
$H_{c2}$ and enhanced diamagnetic magnetization $M$ by Wang et al (PRB 73,
024510), were interpreted as to provide evidence for the pseudogap scenario
which long-range phase coherence is destroyed by thermally-created vortices. We
present here calculations in good agreement with these measurements but based
on the local formation of conventional Bogoliubov-deGennes (BdG)
superconducting regions in doped disordered cuprate superconductors. Our
results imply in an alternate scenario which the disorder plays a fundamental
role in the high critical temperature superconductors (HTSC) physics.
