| Summary: | (pW) in tropical systems are estimated using TIROS 10% of the variance. account for approximately 75% of the variance of PW compared American coast. MJO PW maxima coincide with Outgoing amplitudes up to 2 mm (rms) and accounts for up to 15% of the appears near the equator. Madden-Julian associated with the monsoon. The largest daily variations Daily PW values are used to determine descriptive statistics. dominated by subtropical highs. It accounts for up to 80% of expected from SST changes alone. PW signals associated with extrema migrate annually with the most dramatic shift in daily and mean PW fields and synoptic scale features found Longwave Radiation (OLR) negative anomalies. The lowest stay in the ITCZ and subtropical highs. El Maximum values associate with the Intertropical Convergence moistening can reach 2 cm and is over twice the amount Nino/Southern Oscillation (ENSO) phases affect the PW on daily maps coincide with those seen in microwave data. Operational Vertical Sounder (TOVS) radiances over ten cool oriented wave that adds a north-south dipole as it approaches Oscillation (MJO) phases affect the PW pattern with particularly away from the ITCZ and over ocean areas patterns, but not the regionally averaged amount. The warmer reside in the PW gradients poleward of the ITCZ while the scale. They have PW patterns similar to MJO'S, except for seasons and two entire years. Statistical regression models several cycles longer than synoptic scale are quantified. similarities between the 10-15 d, 15-20 d and 20-25 d cycles suggest they are one feature operating in the 1025 d time The annual cycle dominates over the semi-annual cycle, the dateline. The dipole fades before the wave reaches the the local variance of PW. The semi-annual cycle mostly the north-south dipole. Each fluctuation accounts for up to the phase, the moister the equatorial eastern Pacific. This The spatial and temporal structures of precipitable water to radiosonde data. Large scale features that readily appear variance. The pattern moves eastward as an east-west Zone (ITCZ) and South Pacific Convergence Zone (SPCZ). These |
