Systems and methods for monitoring updrafts in clouds
View Patent ↗A weather forecasting system may receive satellite image samples and identify an updraft and components of the updraft within a cloud. These satellite image samples are collected over time (e.g., at 30 second to 1 minute time intervals). The system may identify an area of rotation and/or divergence at cloud top in a cumulus cloud or mature convective storm over time by comparing the samples and determine a parameter indicative of the updraft based on the area of rotation and divergence. The system may estimate aspects of the environment related to storm development and predict the occurrence of a weather event in the future based on the parameter and generate an output indicative of the occurrence.
1. A system for monitoring updrafts in clouds, comprising:
memory for storing satellite image data defining a plurality of samples, each of the samples defining a satellite image; and
at least one processor configured to compare the samples and to identify a cloud within the samples, the at least one processor configured to track a rotation of at least one feature of the cloud at a top of the cloud based on the samples and to identify an updraft within the cloud based on the rotation of the at least one feature at the top of the cloud, the at least one processor configured to determine at least one variation of the identified updraft over time and determine a parameter indicative of the updraft based on the at least one variation, the at least one processor further configured to compare the parameter to a predefined threshold and provide a warning based on a comparison of the parameter to the predefined threshold.
2. The system of claim 1 , wherein the parameter is indicative of a strength of the updraft.
3. The system of claim 1 , wherein the at least one processor is configured to predict an occurrence of a weather event based on the comparison, and wherein the warning is for the predicted occurrence of the weather event.
4. The system of claim 1 , wherein the warning is for the updraft.
5. The system of claim 1 , further comprising an air traffic control system responsive to the warning for transmitting at least one warning to a pilot of an aircraft for warning the pilot of the updraft.
6. A method for monitoring updrafts in clouds, comprising:
storing, in memory, satellite image data defining a plurality of samples, each of the samples defining a satellite image;
comparing the samples with at least one processor;
identifying, with the at least one processor, a cloud within the samples based on the comparing;
tracking a rotation of at least one feature of the cloud at a top of the cloud based on the samples with the at least one processor;
identifying an updraft within the cloud based on the tracking;
determining, with the at least one processor, at least one variation of the identified updraft over time;
determining, with the at least one processor, a parameter indicative of the updraft based on the at least one variation;
comparing, with the at least one processor, the parameter to a predefined threshold; and
providing a warning based on the comparing the parameter to the predefined threshold.
7. The method of claim 6 , wherein the parameter is indicative of a strength of the updraft.
8. The method of claim 6 , further comprising predicting an occurrence of a weather event based on the comparing the parameter to the predefined threshold, wherein the warning is for the predicted occurrence of the weather event.
9. The method of claim 6 , wherein the warning is for the updraft.
10. The method of claim 6 , further comprising communicating the warning to a pilot of an aircraft for warning the pilot of the updraft.
11. The method of claim 6 , further comprising controlling an aircraft for avoiding the updraft based on the warning.
