Precipitations Eric Angat Teacher

1.Why is freezing rain considered as one of the most dangerous type of precipitation? Freezing rain makes the road slippery resulting to road accidents.

2. What do we need to investigate when determining the type of precipitation? The temperature from the surface to upper troposphere.

3. How does snow form? 4. Describe the temperatures from aloft to the surface when the type of precipitation is snow. 5. How does sleet form? 6. Describe the temperatures from aloft to the surface when the type of precipitation is sleet. 7. How does freezing rain form? 8. Describe the temperatures from aloft to the surface when the type of precipitation is freezing rain 9. Describe the temperatures from aloft to the surface when the type of precipitation is rain. Think!

Snow 28 F 29 F 30 F 31 F 30 F The freezing point of water is 32 F or 0 C. The temperature from the upper troposphere to the ground is below the freezing point of water. Sleet 34 F 33 F 32 F Water freezes at 32 F 31 F 30 F The upper troposphere is slightly above 32 F and the lower troposphere below freezing. Freezing Rain 36 F 35 F 34 F 32 F Sleet: 32 F aloft Freezing rain: 34 F aloft 33 F 32 F Water freezes at 32 F 31 F warm temperatures aloft, generally several degrees above freezing, produces rain that falls onto a surface with temperatures below 32 degrees. Aloft = higher troposphere

3. How does snow form? 4. Describe the temperatures from aloft to the surface when the type of precipitation is snow. 5. How does sleet form? 6. Describe the temperatures from aloft to the surface when the type of precipitation is sleet. 7. How does freezing rain form? 8. Describe the temperatures from aloft to the surface when the type of precipitation is freezing rain 9. Describe the temperatures from aloft to the surface when the type of precipitation is rain. Think!

3. How does snow form? 4. Describe the temperatures from aloft to the surface when the type of precipitation is snow. Snow forms when the temperature from the upper troposphere to the ground is below the freezing point of water. The temperature from aloft to the surface are all below the freezing point of water. 32 F

5. How does sleet form? 6. Describe the temperatures from aloft to the surface when the type of precipitation is sleet. Sleet forms when the upper troposphere is slightly above 32 F and the lower troposphere below 32 F. Upper troposphere is slightly above 32 F and the lower troposphere below 32 F.

7. How does freezing rain form? 8. Describe the temperatures from aloft to the surface when the type of precipitation is freezing rain Freezing rain forms when temperatures aloft is warm, generally several degrees above freezing, produces rain that falls onto a surface with temperatures below 32 degrees. Temperatures aloft and mid-troposphere is above 32 F but below 32 F on or near the surface.

9. Describe the temperatures from aloft to the surface when the type of precipitation is rain. Think! The temperatures throughout the troposphere and surface are all above 32 F.

Water table groundwater Flood happens when the water table rises above the surface. 10. What happens when the water table rises above the surface of the earth?
