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).
Modern weather radars are mostly doppler radars, capable of detecting the motion of rain droplets in addition to intensity of the precipitation. Both types of data can be analyzed to determine the structure of storms and their potential to cause severe weather. Precipitation type is indicated by the color-green is rain, pink is a mix of rain, freezing rain, sleet, and/or snow, and blue is snow. Digital radar systems now have capabilities far beyond what their predecessors only dreamed of. Digital systems now offer storm tracking surveillance.
