| Characteristics of the Intertropical Convergence Zone (ITCZ) in the eastern Pacific are derived from the monthly mean wind convergence of ERS-QuikSCAT fields for 1991-2004. Its climatology is computed over 1999-2004, and compared with those derived from monthly sea surface temperature, atmospheric water vapor, cloud liquid water, and rain rate from the Tropical Rain Measuring Mission (TRMM, 1999-2004). Preliminary results indicated an excellent relationship between wind convergence and TRMM data for the northern branch of ITCZ (NITCZ). However, none of the TRMM fields show, as the ERS-QuikSCAT fields does the southern branch of ITCZ (SITCZ). Therefore, an especial emphasis is given over SITCZ, for instance only shown in wind convergence, with a permanent... |
