At Chichén Itzá, in order to obtain rain, victims were hurled into a deep natural well (cenote) together with copper, gold, and jade offerings.
During the sixth month, Etzalqualiztli, the rain priests ceremonially bathed in the lake; they imitated the cries of waterfowls and used magic "fog rattles" (ayauhchicauaztli) in order to obtain rain.
The obtained rain rate model explicitly depends on parameters for a typical tropical cyclone wind field simulation, namely storm location, approach angle, translation speed, radius of maximum wind, pressure profile, surface drag coefficient, and turbulent diffusivity.
Consider sending your blinds to the cleaners, or do it yourself: If your blinds are too long for the bathtub, obtain some rain gutter.
Hourly cumulated rainfall histograms obtained from rain gauges on November 4, 2011 are reported in Fig. 9 (circles 1 and 2 on the right and left, respectively).
He then obtained worldwide rain samples from the International Atomic Energy Agency, which collected samples to track radiation from bomb tests.
Figure 12 shows the hourly cumulated rain obtained from four available rain gauges near the GENO and GENU PSs and their relative positions.
Epiphytes obtain water from rain and water vapour in the air; most absorb water with their roots, though many have specialized leaves that also take in moisture.
It can be seen that it only take 1.22 s to obtain the final rain removal image, whereas that with method [10] is 12.74 s, with method [6] is 31.40 s, with Luo's method [5] is 61.35 s, and that with Huang's method [3] is 26.86 s.
Two different rainfall simulator designs were developed in order to obtain variable rainfall intensities with drop sizes and energies similar to natural rain.
Firstly, a weighted median filter is convoluted with an input rainy image to obtain a coarse rain-free image; then, guided filter is employed to obtain a refined rain-free image, where the coarse rain-free image is used as a guided image and convoluted with the input rainy image via guided filter.
