使用测雨仪数据对位于阿拉戈斯马塞北方沿海板（西经933'17.24'和3546'54.84'）的一个地区的降雨物理学进行研究的初步结果，该地区海拔约80米。这些数据是在2002年1月期间使用disdrometer RD-69（Joss-Waldvogel）获得的。在确定了对流型和层状型雨型的判别标准后，利用一组Z-R对，对每种雨型的Z-R关系进行了分析。结果与地球仪其他区域的结果十分相似。这一初步分析将用于研究气象雷达降雨的结构，并有助于更好地了解热带降雨的物理学。
The preliminary results of the study on the physics of rain using disdrometer data are shown for an area located on the northern coastal board of Macei, Alagoas (933'17.24' and 3546'54.84' W), at approximately 80 meters above the sea level. The data were obtained during January 2002 using a disdrometer RD-69 (Joss-Waldvogel). After definining the criteria for determining rain type (convective and stratiform), a set of Z-R pairs was analyzed for estimating the Z-R relation for each rain type. The results were quite similar to those for other regions of the globe. This preliminary analysis will be used to study the structure of rain with the meteorological radar as well as to permit a better understanding of the physics of tropical rain.
