Snowfall map7/15/2023 The colder the snow, the stronger this sound can be perceived. Where does this crunching and cracking come from when walking in the snow? Basically, you hear nothing other than the breaking of individual ice crystals in the snow. Why does snow crunch when you walk in it? This hexagonal shape allows the water molecules to form as a crystal very efficiently. The shape of snow is related to the special structure of a water molecule: Due to the electrical charge of the single atoms, these molecules can only arrange themselves in a hexagon or at an angle of 60 degrees or 120 degrees. For this reason, we see different spots flashing in the snow as we move through the multitude of ice crystals. The uppermost layer of the snow cover, with its countless snowflakes, reflects the light to our eyes directly and without further refraction. The glitter in snow can also be traced back to the reflection of light by the ice crystals. Therefore, the snowflake appears white to the human eye. However, when sunlight falls on the snowflakes, this light is refracted several times by the special shape of the flake and reflected through the trapped air in the snowflake. Under the microscope, snowflakes appear to be transparent. The white color of snow depends on the particular shape of the snowflake. Interesting facts about snow: Why is snow white? Apart from the snow cover map, the cloud radar, tornado radar, rain radar, lightning strike map and storm radar also function in the same way. Using this measurement technique, an accurate picture of the current precipitation area can be created and continuously updated within only a few seconds. Depending on the temperature on the ground and in the air, it can be predicted whether rain or snow will fall. The more radar waves hit back to the measuring station, the more precipitation is available in the cloud. These radar beams are sent back to the radar station by the water droplets in the cloud. With the help of a radar station, microwaves are sent into the clouds. The function of a precipitation radar (snow or rain radar) is always the same. How does a snow cover map work in practice? A violet coloring suggests that you should expect heavy snowfall. A green or blue coloring means weak to moderate precipitation. The snow is also displayed in color on the map. The current snowfall is colored with snowflake symbols on the map. You will then see how much snow you can expect in the next 12 hours. You can simply move the snow marker to your desired location with the mouse (or on the cell phone: hold down the white dot of the marker with your finger). This allows you to conclude how precipitation will change over the next 36 hours and whether you should expect snowfall in your region over the next few hours. Using the cursor at the bottom left of the snow cover map, you can visualize the future course of the snowfall. Beyond this, the snow cover map offers further useful functions: This thunderstorm is also indicated by a lightning symbol on the map. In some cases, heavy snowfall is accompanied by a thunderstorm (the so-called “blizzard”). In areas colored in violet, you can expect an amount of new snow of more than one meter in the next few hours. The colors range from blue and green for light snowfall to violet. Where is it snowing right now? Is there snowfall in your region? This is how you read the snow cover map:Īll areas where snowfall is expected are shown in color on the map. Please consult with local authorities before venturing onto ice covered lakes, ponds, or streams.The current snowfall is colored with snowflake symbols on the map.
