| 英文摘要: | This study presents the first analysis of small-scale convective structures observed in a total column water vapor (TCWV) field obtained from full-resolution Medium Resolution Imaging Spectrometer (MERIS) near-infrared measurements. The high-resolution MERIS TCWV field for a high-pressure event occurring in May over central Europe allows the detection of horizontal convective rolls, due to the observation of parallel bands of alternating low- and high-TCWV values. The bands are aligned parallel to the boundary layer winds obtained from a numerical weather prediction model and radiosonde data. Closer examination further reveals that cloud streets observed in the east extend along bands of maximum TCWV. From a quantitative analysis of the TCWV data, combined with auxiliary data, it is shown that the roll wavelength and aspect ratio can be determined, which are found to be 6.5 km and 4.2, respectively, for this case study. Key Points A high-resolution TCWV field is retrieved from full-resolution MERIS measurements It allows detailed satellite observations of horizontal convective rolls The observed rolls have wavelengths of about 6.5 km and an aspect ratio of about 4.2. © 2015.
