If you eat dairy, there are multiple options for milk products with ample calcium. But if you avoid dairy, you still can find calcium: just look for tofu or canned fish with bones. Some orange juice brands also contain added calcium (as with vitamin D-fortified products, just make sure to buy only gluten-free juice).
In winter especially, the rain clouds can be below the radar beam at a distance of more than 200 kilometres from the radar, and hence the radar beam will overshoot the rain. As a result, the radar image will not show any rain even though at the ground level it may be raining at the time.Due to the reasons described above, interpreting the radar images at extended ranges can be difficult and you should take great care in using these images.With practice, however, you will find them useful.hus precipitation that is occurring some distance away from the radar might not show at all, or may show with a reduced intensity. The presence of significant echoes at large range probably indicates the presence of large amounts of rain at high levels above the ground (e.g. a thunderstorm).
The simple answer is that they reflect very well the light that falls on them. Clouds are illuminated by light from the sun, and light from the sun is seen as white by our eyes, a mix of all the colours of the rainbow - which produces white. Clouds are made up of many small water drops and ice crystals.
